What Is The Importance Of Software Testing?

There is an entire phase in the SDLC dedicated to software testing. Traditionally, it’s done after the developers have finished building the software – it’s handed over to the testing team to perform tests on it. This is, in my opinion, the most important part of the SDLC process.

The reason it’s so important is that it is the major factor in getting good quality software. Developing software that works and works well is the ultimate aim of a project, and the testing stage is where this is done.

The software testing phase can be broken down into smaller stages, each of which have their own importance:

Unit Testing – testing each component of the software individually, to check that it works correctly in isolation.

System Testing – testing the entire system as a whole, ensuring all of the components work as expected.

Regression Testing – testing the entire system against a pre-defined list of tests, to ensure the new changes don’t impact existing functionality. This is important for upgrades and updates to software.

These are the main types of software testing and each of them are important. I believe there are three main reasons that we do software testing.

Software Testing Results In Less Maintenance

The aim of software testing is to ensure good quality software. Good quality software means it has less defects or issues, it works well, and does what it needs to do. When you do software testing as part of a development project, you are aiming to pick up and find all of the issues in the system before it is release to the end users.

In an ideal world, the developers will be creating software that works first go, and does not have any issues. However, this is not often the case – bugs appear in the system and the software testing phase is there to pick it up. If it’s found before the release, that’s great. If it’s found after the release, it means that time will need to be spent finding a fix and performing more testing on it – all while the end users are using the software.

The time taken to fix defects after the software is released is significantly more than during the testing phase. This is because the fixes need further testing, and need to align to any maintenance releases or other schedules that the organisation has set up. Getting it right the first time when you release it is almost always the preferred approach.

Good Software Testing Results In Increased User Morale

As mentioned above, fixing the bugs in the system before the release is preferred. Another benefit of doing this is that the user morale and confidence in the software is increased. Why is this?

Well, let’s say Project A has completed but software testing was not done very well. The software works, but not very well, but is still released to the users. They start using it, and even though it does some things well, there are still outstanding issues so some parts don’t work as expected. This results in the users getting frustrated with the tool – which is not a good thing for the organisation or the project team. The defects may eventually get fixed, but the reduced morale from the users will take time to heal.

Alternatively, Project B has completed. They have spent more time on software testing and when it is released, it has far less defects. It has taken longer to produce, due to the increased focus on testing, but once the users have it, it will work correctly and they will be happy with the software.

The testing effort and decision may be impacted by the organisation you work for, and other factors, but the benefits to user morale are high.

Software Testing Matches The Product To The Requirements

The final reason software testing is important is that it is used to match the software to the requirements.

Software is built around the user requirements gathered during the analysis phase of the project. The analysis phase defines what the software is supposed to do. The developers aim to build from these requirements, but it’s the testing phase that checks that these requirements have been met.

The testing is done against functional requirements – such as expected behaviour and what needs to be done. It checks that the software does what it supposed to do, and that nothing has been done incorrectly or left out. It also checks non-functional requirements – things such as load time and other performance measures.

What If We Didn’t Do Software Testing?

One question people might wonder, is what if we didn’t do software testing? What if the developers just created the software and released it? That is one option – but I don’t think it’s a very good one.

It would rely on the developer actually creating low-defect software – which isn’t very likely. All developers (myself included) think that their software is bug-free, but in reality, issues are always found.

Releasing the software without testing will mean there is a high risk of issues being found, and the software not actually working. It would waste a lot of user time and effort when using it. It may actually result in more serious issues, such as security breaches, data loss and corruption.

In summary, the importance of software testing can be attributed to three areas – less maintenance, increased user morale, and matching to requirements. It results in high quality software – which should be something all of us are aiming for.

Many business people don’t fully understand the complexity of a software development process. It’s natural, since specialized books about development are read by developers and other IT people, and many others might still be referring to a software project as ”coding” or ”writing”. With better luck one might add ‘designing’ and ‘testing’. Quite inaccurate.

One can think of several metaphorical comparisons to describe software development, such as writing a book or building a house. Some of them are a good light in the dark, some are rather misleading. And while many people may argue whether creating software is an art, a science, or a precisely elaborated process, we’d leave that choice to someone else. It cannot be described sparsely. But we’ll try to give some descriptions and comparisons in a compact and clear way.

Do We ”Write” Software?

One of the common but rather vague things is comparing creating software with writing. Writing code, writing a book, and so on. You can start writing a book without a plan and go with the flow; with custom software development you cannot, unless developers do a rather small piece of software on their own – and for themselves. Moreover, an outsourced software project never starts with writing code.

Books and software may both have strict deadlines. But once a book is published, what’s written is written; rewriting is not an option. But software keeps being under constant improvement with new versions being released – it’s a natural thing. It’s almost impossible to get every need of your end user, catch up with business and technological changes once and for a lifetime. Books aren’t that dependent on changes; software is. But that’s good: your software, unlike a book, can’t become just another mediocre thing on the market, can’t become irrelevant and outdated. The processes are absolutely different: we prefer using the words ”create” or ”build” software rather than ”write”.

Do We ”Grow” Software?

”Growing” software on a good basis and a good set of documentation is possible to a certain extent. Like with writing, it’s not the best description one can suggest. It partially gets the incremental, agile nature of making and maintaining relevant software. But while ”growing”, the product is rarely tasty until it’s ripe, and the owner has to wait awhile.

The difference is, in software development there are different stages of being ”ripe”. Startups usually demand rolling a minimum viable software product on the market, getting feedback and making corrections and improvements. Each version is more ”ripe” than its predecessor, and it has to be ”watered” by support and maintenance, kept fresh amidst all the business and technological changes.

Do We ”Build” Software?

This one is considered by many specialists the closest way to describe software development, and we can agree with that. Construction works show the huge importance of careful planning, preparing, guiding the work, and performing it. The limits of software depend on how its architecture is constructed. The amount of works doesn’t grow gradually, since every building is different, and requires different approach. There can be a hospital, an office building, a school or a barn, and same physical size doesn’t mean equal amount of labour. Something is done with concrete, something can be done with wood and nails, and the latter doesn’t work well with complex and valuable software for mobile startups and other businesses.

– Everything depends on the kind of a building you need. You need to figure out the problem the software will solve, and conduct the necessary preparations, do market research, gather info, etc. The more complex your software is, the more resources must be spent on planning. Bad planning – and the whole app fails, falls like a house of cards by the first gust of a wind.

– Then you and your chief architect (project manager) can proceed to design that perfectly combines functional requirements and interface, resulting in proper user experience. Sure you want those who will work or live in the building to be fully satisfied with it. Same thing with software. One more good thing, once the design is approved, it’s way easier to give more precise estimations for the remainder of the construction (development) works.

– When furnishing a house, you needn’t building things you can buy: household appliances and furniture. It’s much cheaper and way faster. Same with software: if your software development team is experienced, it will use all the available resources to stay away from writing needless basic things: there are lots of software toolkits, frameworks, classes, and libraries for that, each for a particular case. And if the team means business, they will easily find tools and technologies that will get your tasks done as fast as possible. Custom pieces of furniture take more time and efforts, but in most cases there are already existing pre-built ways to save your time and money without compromising security and efficiency of your software.

– There will always be changes in functional requirements. Again, changes can painlessly happen within the planned architecture. Here we once more emphasize the importance of preparations – although this topic is worthy of a separate article. And we cannot go anywhere without mentioning quality assurance, which constantly checks different aspects of how the software works. What’s more – even a minor change involves testing, so that’s not the place to cut the costs (in fact, QA usually takes about 30% of the whole development time).

– Optimization of software (inner walls of a building) is limited to the approved architecture, and here main expenses are all about labour, not materials. But what you receive in the end is better software and satisfied users. Meanwhile users speak their minds on what they would like the apartments to look – and one should never neglect these opinions.

A set of instructions for the computer to read and understand to perform a specific task is called a Software. Software development is the process to use computer programming to develop a software. This is not new for many, but the topic under consideration will be new for many. SDLC or Software Development Life Cycle, is the process of developing a new software.

The process of developing a software is not difficult to understand. The procedure of SDLC goes like this:

Gathering and then analyzing the requirements to develop a software
Designing of the software
Coding or programming
Testing the software
Deployment
Maintaining the software

Gathering and Then Analyzing the Requirements to Develop a Software

This is the initial phase. Like starting any business, starting to work on a new software requires a plan. The planning phase will include the project managers, stakeholders and even some senior software developers. No matter how professional or for how long the software development company has been operating, the planning is not an easy phase to follow. Although, it would take less time for experts to plan a new project and then to start working on it but still there will be some questions that must always be answered before taking on any project. Following are some questions, which needs answers before taking on the project:

Who will be using the software?
How they will be using it?
What is the required data to input?
What will be the output of the input data?
What is the purpose?
What skills are required?Will there be a need to hire new personnel or the current staff have the right skills and the capacity to work on this new project?

Find their answers. Is the project worth it? A thorough analysis is required here. There will be more questions that need to be answered before taking on this new project. All the work is documented for future reference.

Designing of the Software

Now comes the second phase, the designing of the software. On the basis of the documentation and the results of the first phase, the system and the software is given a design. From this, the developers comes to know the requirements of the hardware and system required to complete their new project. This phase will also define the system architecture. The designing phase will set the requirements for the next phase.

Coding or Programming

Here comes the role of the software developers. The system design documents are now divided into modules and the developers now start their job. This is going to be the longest phase of all. Programming is done here and it’s known to all that programming isn’t an easy job. It needs plenty of time, expertise and patience. Once done, the software developer sends their work to the tester.

Testing the Software

When in the production business, the quality of the product is always monitored and tested. So is the case with a software development. When the coding is done, the software developer sends their work to the Software Quality Assurance department /personnel. They will overlook the work of the software developers. The software quality assurance or the SQA for short will look for bugs and test the software. The test will be made as per the requirements and the guidelines mentioned in the requirements document. Unit testing, integration testing, system testing, acceptance testing is done by the SQA and if found deviations or errors, it’s sent back to the software developer. The procedures will keeps on repeating themselves until the software is bugs free and ready to deploy.

Suppose you are developing a desktop application. You would definitely pay attention to it’s overall and detailed design. Things like button design, loading spinner , icons, fonts and other element should never be forgotten about. They all make your design a whole. This is the same for users. Never forget that users like well stylized apps too.

Open Source Software (OSS) has gained considerable importance in the software industry with extensive development and is now being widely accepted as a new model of business. The open source model is far more acceptable today due to the decreased degree of defects and errors as compared to proprietary software.

Technical Variations

Open source software, as the name suggests, allows accessibility to source code of a software program in order to make modifications to the software. Issues surrounding accessibility involves drafting licensing of the software in a manner which allows access to the source code. Whereas, in proprietary software the source code is not shared, viewed and modified. All modifications are done by the software developer as per the licensing agreement. Users of the proprietary software are required to purchase any upgrades of the existing software from the author of the software, as users are prohibited from copying, distributing, and modifying the software.

Although deviations have altered the arrangement between a vendor and customer of proprietary software, users are allowed to view and modify the source code without distributing it others. An example would be Microsoft’s Shared Source Initiative (SSI) which allows the user to adapt its proprietary software as per their requirement by allowing them to make modifications in the source code.

Usability

A major point of difference between open source and proprietary software is the element of usability. OSS not reviewed by professional testers does not cater to a greater audience. Users generally discuss issues associated with an OSS in forums, online communities having fine documentation, news groups, and even live chats to review and modify the code base as against the proprietary software.

Enhanced Targeting of Customers

Users of open source software act both as the innovator and user.The software is targeted on the users and proprietary software, whose users and developers, are different so user requirements and expectation from the software might not be gauged correctly. Open source software allows for greater customization.

Cost Factor

OSS versions are released regularly and come free of cost. Proprietary software versions are released from time to time and needs to be bought. Highly priced compulsory virus protection, up-gradation expenses, support expense, and vendor-lockin involves high technology cost to a business opting for proprietary model.

Interoperability

Open source software is better in sticking to open standards in relation to other businesses, computers, users, and is not restricted to the proprietary data formats.

Innovation

OSS enables high levels of innovation by a large number of skilled people who can make modifications in source code for improved performance as per user demands and requirements. Proprietary software involves huge costs on research and development by a restricted number of developers writing the code. The team size might change with fresh applicants who may or may not have the capability to completely understand and write the particular code with the same level of efficiency.

Security

Due to the organizational nature, proprietary software is developed by a team of developers with a common goal in a restricted environment. The source code is accessible only to the team members who can modify the source code as per the requirements. This lowers the chances of error and bug penetration in the source code considerably. The level of security for the software against viruses is quite high in a proprietary model. With the OSS model, software is developed in a controlled situation, in a non-continuous structure, without a single objective and without communication between software developers. Lack of validation increases the possibility of virus.

However, there is a flip side. In open source software, a lot of people can access and view the code source, thereby making the possibility of bug detection quite certain.Quoting Linus Torvalds, founder of LINUX, “Given enough eyeballs, all bugs are shallow”. OSS allows a lot more people to view and test the code thereby making flaw detection and fixing quite viable. Bugs detected in open source are fixed quicker. Developers of proprietary software on the other hand, might take weeks or even months to track a flaw and patch it up.

Changing Landscape

More companies are adopting the OSS model which has led to drastic reduction in technology costs, making OSS a feasible option for many small and medium sized enterprises, who can have Live CD’s and USB’s for LINUX software distribution.

Many large companies such as IBM and HP are considering open source software and the trends are going to spread at a faster rate for other companies too.

There has been a shift from the proprietary software model to open source software model, giving some serious competition to proprietary software makers. As for the open source software, just having enhanced view would not prove to be sufficient, even open source requires better tools for gauging defects effectively by users.

Every business has diverse requirements and needs to implement efficient software solutions which can improve work flow, processes and output. Most of the software in use is called Commercial Off-the-Shelf Software, also known as Packaged Software. This software can fulfil the requirements of many organisations but is not suitable to the meet the specific needs and expectations of every client. On the other hand, Bespoke Software (or Custom Software) is built as per the exact needs of a business. It can adapt to the current requirements as well as future needs of a business. This makes the process smooth and improves the working efficiency. Many organisations prefer to develop a Bespoke Application which is tailored to meet the needs of the organisation.

So, which type of software should an organisation or an individual use? There are two sides of the same coin. Similarly, Bespoke Software and Custom Software have their benefits and disadvantages. Let us discuss this further in order to help organisations to take the right decision.

The ADVANTAGES of Off-the-Shelf Software

The first benefit for any organisation is that Off-the-Shelf Software is relatively cheaper than Bespoke Software since there are many end users.
This software offers more number of features as more resources have been used for its development. This is possible because the revenue earned from such software is higher than Custom Software.
Support, maintenance services and help manuals for this software are easily available (at a lesser cost) as a large numbers of users are using the software.
It is easier to share files since it is likely that other users are also using the same software.
There is no need to spend time on the development process.

The DISADVANTAGES of Off-the-Shelf Software

This software is highly complicated and may require a lot of time to learn. It has many features which are not used at all.
By its very nature this software is designed for a large number of users. So, the organisation will need to adapt and alter work practices which meet the requirements of the software, and not the other way around.
You cannot gain an edge over your competitors as everyone has access to the same software.
The organisation has no control over the development and thus cannot make any changes to the software, even if it feels the need to do so.
If an individual faces some problem, then his concerns may take a long time before the organisation solves the issue.

The ADVANTAGES of Bespoke Software

Bespoke Software is designed to meet the specific requirements of an organisation. So, it is perfectly tailored to the needs of a business and operates accordingly.
This software is developed as per specific needs and is flexible. It can solve existing issues easily and has the potential to adapt to future needs as well.
Bespoke Software can easily integrate with existing systems and provide a fully integrated IT infrastructure.
It provides an easier and intuitive user interface. It does not contain unnecessary features which are not of use to a particular organisation.
In case users face any problems, they can directly contact the developers and get the issue resolved quickly. It saves precious time and resources.
The developers of Bespoke Software can suggest more options and innovative features to improve productivity and efficiency of an organisation.
An organisation can gain an edge over the competition by using Custom Software as the competitors are not using the same software.

The DISADVANTAGES Bespoke Software

This software is developed by a single company, so requires a higher investment initially for the development as compared to Packaged Software. A business needs to compare the costs and the expected benefits in order to come to the right conclusion.
It is important to be wise in choice of developers. You need the services of an experienced and a highly professional team who follow the best industry practices to develop Custom Software. An inexperienced team can deliver software which is unstable and has many bugs.
It is important to get a copy of the source code; else an organisation will be dependent on goodwill of the developers
This application is designed to meet specific needs and can take a longer time to implement.

Most business organizations today are quickly adopting the use of custom ERP software solutions because as opposed to the common use of manual procedures and legacy applications, ERP programs are cost-effective and efficient. The Enterprise Resource Planning program is a system of integrated applications that are designed to automate different department/office operations (product planning, development, manufacturing, sales and marketing) to a single database.

Nevertheless, not all ERP software will meet to every requirement of your organization. Therefore, when deciding on the ERP software to adopt, you need to choose the most reliable one as far as your business needs and processes are concerned. In turn, here are the two types of ERP systems:

Off-the-shelf

These are systems easy to implement due to the fact that they are developed out of the experience of other organizations (user groups) other than yours. From the discussions on how each of those companies’ best use the system, you acquire information on how best to adopt the system for your business.

Custom ERP software

With custom ERP, the system is developed based on your company’s experience. A programmer gets to design the ERP system in accordance what exactly you want the software to be able to do and ideally, the process it should follow in order to do perform and facilitate your operations.

WY COMPANIES CHOOSE CUSTOM ERP SOFTWARE
There is a greater chance of a company meeting its user requirements when it goes for custom-built ERP software other than a generic system solution. This is so despite the high upfront costs and time consumption to get the system started. You can always start small and add the essential layers as you go by and in the end meet, the target software for your business. Plus, it is also a way to spreading the initial expenses throughout.

Custom ERP software is also designed to fit your business processes instead of the business fitting into it, this is somehow relieving since as far as training of the company’s staff is concerned, there will be less of it. All they have to do is make little adjustments to coordinate with the system.

A good example of such approach is Tesla, who carefully evaluated all pros, cons, and risks and decided to build custom ERP solution having above mentioned benefits in mind. Tesla CIO Jay Vijayan calculated the costs of SAP implementation in “millions of dollars” and a year to perform all the required integrations. Tesla managed to achieve same functionality within 4 month and much lower budget with custom built ERP. As the result, they’ve got independence from third-party vendor and Enterprise Resource Planning System that is tailor-made for their established internal business and manufacturing processes.

HOW MUCH IT WOULD COST TO BUILD CUSTOM ERP SOFTWARE
It is obvious that the cost of custom ERP software development would depend on what you require, the number users and its complexity. For instance, if you are going for a sophisticated custom ERP system, you might not find complete designs that fulfill your needs. Therefore, you will have to incur extra cost for complimentary products to ensure the software fully functions.

Nevertheless, the general cost of the ERP system will range between $25k to 75k. The extra incurring costs for future modules or top-up services and tools would go for $5k to 25k.

RISKS OF DEVELOPING CUSTOM ERP SOFTWARE
The solutions and services that custom ERP software development is meant to provide, is usually not in box therefore, it requires a lot of time and finances to initialize the design resulting to high upfront fee.

Since development of a custom ERP software is on basis of your requirements, to get a high-quality system that maneuvers around future changes easily despite it being a first-time project, you require a developer with experience. Such resources are hard to come by as you are outsourcing.

In addition, your contact with the developer who initialed the system needs to be consistent. This is because they would understand the system better during the development cycle: design, testing, QA/ testing, and training. This may be hard to do especially if the developer is not reliable.

Despite that, custom ERP software helps to save an enormous amount of money in long-term perspective. You may ask how is that possible. Each company counts on continued growth, including the number of employees, field force, and offices. In many cases, a bigger number of users means the continually growing expenses for the licensed ERP solution. Enterprise support packages are often sold as extra services and are way more expensive than support from the custom software development provider whose support is often included in the contract. Also, it is worth to mention that your organization will be the only one supported for the product which means better and faster communication.

So, the expenses for the existing user licenses, new licenses, and support of the off-the-shelf solution is growing exponentially and completely overlap custom ERP software development costs in a couple of years. In its turn, custom ERP software will justify its high upfront costs, because your enterprise won’t be locked to the provider, will own the solution and all the data stored in the cloud as the result, and won’t pay for licenses when new user accounts will be needed.

CUSTOM ERP SOLUTIONS EXAMPLES IN DIFFERENT INDUSTRIES
From the advantages of the existence of a software that can meet your business requirements and solutions, most companies have been seen heading to custom ERP system development for the management of their operations. Below are a few of such companies:

Oil and Gas Companies
Oil and gas companies have a great plus with custom ERP software development but, it is usually a tragedy if the system does not support the operations efficiently. Therefore, when going for a tailored system for such a massive company more considerations are put in place other than the obvious; meeting the user needs.

Custom ERP software for gas and oil companies should most importantly have applications to handling the environment safety. Energy companies are known to be hazardous to their environment and if not taken care of it would cause damage and to some extent shutting down of the organization. Therefore, the system should be able to provide data to the technicians as warnings in case of any threat so that they can mitigate the risks.

Also, other than facilitating the operations of the company, a custom ERP software development should be able to open up opportunities for high profit returns investments for the business. That is, it should have a cost management application too.

Finally, oil and gas fields are known to be really massive and some are usually in dense remote areas but since it’s business, every asset should be accounted for. In turn, a custom ERP software with good networking is essential to integrating and managing all the company’s operations regardless of the location. Such location difficulties are curbed with high-tech optimization tools to managing all labor and resources throughout.

Manufacturing companies
With manufacturing firms, custom ERP system are saviors when it comes to saving costs, eliminating office paperwork, tracking business performance and improving customer experience. This is made possible by integrated custom applications platforms for management of its operations.

Nevertheless, managing a national or to some extent international business operations can be a challenging task. A centralized custom ERP software can however, bring light to all your businesses processes as it enables management of creation of product, marketing and availing of the product across all the decentralized outlets. In addition, it integrates all that data thus incorporating workflow and control automatically.

Education (schools)
Schools that are going for complete computerization of their functions and processes have custom ERP system development to opt for. A great number of schools have been seen heading to this direction with use of highly tailor-made programs to handle the school management and they are known to be very successful.

Whether it is nursery/ kindergarten, high school or colleges, custom ERP systems have proven to provide efficient management of the institutions.

WHAT ADVANTAGES WILL YOU GET IF DECIDE TO DEVELOP CUSTOM ERP

A custom ERP software is more of a prototype system whereby you can start designing the most basic and important features and function that you have in mind then later, during testing and maintenance, you can add other essentials bringing you to a very efficient software.
With a custom-tailored system, you are likely to achieve the solutions or attain the services you are going for from a software seamlessly.
The staff is usually at an advantage of comprehending how the system works easily because it was designed in accordance to the business practices and language. In turn they have little to adjust on their side.
Custom ERP systems are usually flexible in terms of future technological or even business changes. There is always a capacity for incorporating any developing trends.
Unlike the offshore system, you get to own the custom ERP system and its design is made specifically to meet your needs. Therefore, you need not to wait for feature requests and enhancements as you are in complete control of the system.

In summary, the basic things you need in hand while planning to adopt custom ERP system is you have to budget for high upfront fees. You will require a team of tech-experts from programmers, quality controllers, database engineers to designers and probably more. Then there is patience needed too, developing software that uniquely fits your business, just like Rome cannot be built in a day. It will require a lot of work which will consume time months or even year.

Nowadays, the user experience delivered by a software application determines its popularity and profitability. The user experience delivered by an application depends on its accessibility, functionality, performance, usability, and security across various devices and platforms. Hence, it becomes essential for enterprises to focus on the quality and user experience of their applications throughout the software development lifecycle.

Many enterprises nowadays implement formal software testing strategy to launch a high quality software application. Also, many businesses nowadays test the software continuously and under real user conditions. But several entrepreneurs still do not realize the importance of testing in the software development lifecycle, and the benefits of testing the software early and continuously. They are still sceptical about the benefits of software testing and believe several software testing myths.

Decoding 7 Common Myths about Software Testing

1) Testing Increases a Software Application’s Time to Market

While developing a new software application, enterprises explore ways to beat completion by reducing its time to market. The QA professionals have to invest both time and effort to evaluate the software’s quality under varying conditions and according to predefined requirements. That is why; many businesses believe that the software testing process increases the product’s time to market. But each enterprise has several options to get its software tested elaborately without increasing its time to market. A business can easily reduce testing time by automating various testing activities. Also, it can implement agile methodology to unify the coding and testing process seamlessly.

2) Testing Increases Software Development Cost

An enterprise has to deploy skilled testers and invest in robust test automation tools to evaluate the quality of the software comprehensively. That is why; many entrepreneurs believe that software testing increases software development cost significantly. But an enterprise can reduce software testing cost in a number of ways. It can opt for open source and free test automation tools to reduce both testing time and cost. Also, the software testing results will help the business to generate more revenue by launching a high quality software application, in addition to avoiding maintenance and correction cost.

3) Test Automation Makes Manual Testing Obsolete

The test automation tools help QA professionals to execute and repeat a variety of tests without putting extra time and effort. Hence, many enterprises explore ways to automate all testing activities. The entrepreneurs often ignore the shortcomings of various test automation tools. They forget the simple fact that test automation tools lack the capability to imagine and make decisions. Unlike human testers, the test automation tools cannot assess an application’s usability and user experience precisely. Nowadays, a software application must deliver optimal user experience to become popular and profitable. Hence, an enterprise must combine human testers and test automation tools to assess the quality of its software more precisely.

4) Elaborate Testing Makes an Application Flawless

While testing a software application, testers perform a variety of tests to evaluate its accessibility, functionality, performance, usability, security, and user experience. They even identify and repair all defects and performance issues in the software before its release. The test results also help enterprises to decide if the software meets all predefined requirements. But the user experience delivered by an application may differ according to user conditions and environments. The testers cannot identify all bugs or defects in an application despite performing and repeating many tests. Hence, the business must be prepared to get the bugs or issues found in the application after its release.

5) Developers are not required to Test the Software

An enterprise must deploy skilled QA professionals to get the quality of its software assesses thoroughly and effectively. But it can always accelerate the software testing process by making the programmers and testers work together. The developers can further assess the quality of application code by performing unit testing and integration testing throughout the coding process. Likewise, they must perform sanity testing to ensure that the software is functioning according to predefined requirements. Agile methodology further requires enterprises to unify software development and testing activities to deliver high quality software applications. The project management approach requires businesses to test the software continuously by a team consisting both programmers and testers.

6) Testing Process Commences after Software Development Process

The conventional waterfall model allows business to start the software testing process after completing the software development process. But the conventional software testing model does not meet the requirements of complex and cross-platform software applications. A steady increase is being noted in the number of enterprises switching from waterfall models to agile methodology and DevOps. As mentioned earlier, agile methodology required businesses to test the software continuously, along with making the programmers and testers work as a single team. Likewise, DevOps requires businesses to unify software development, testing, and deployment processes. Hence, the testers nowadays start testing an application from the initial phase of the software development lifecycle.

7) No Need to Deploy Skilled Software Testers

Many entrepreneurs still believe that the only task of a testing professional is to find bugs or defects in an application. The even do not consider software testing requires skill and creativity. The misconception often makes businesses get their software tested by random people. An enterprise can involve real users in the software testing process to assess the application’s usability and user experience more effectively. But it must deploy skilled testers to get the software evaluated under varying user conditions and environments. The skilled testers understand how to identify the defects and performance issues in the software by creating many test scenarios. The even produce elaborate test results to facilitate the decision making process.

There are three basic types of software, although these do have their own subsections, as will be discussed later:
1. Commercial software, purchased with a licence for one or more computers. This generally is coupled with some form of support and regular updates to patch errors etc. Sometimes a new version of the software is offered at a reduced rate as “update”. This type of software is generally relatively expensive and is often designed to cover specific industrial purposes. The big exception is the various sets of “office” software, which are designed for use in the commercial environment, but can naturally be equally used for various tasks at home. The most common application in this category is, of course, text editing. Most of the other classic “office” applications, such as calculations and data bases are only of limited use in the domestic environment, although they will be used in some cases, particularly now that the more computer-literate generation is growing.
2. Simplified or “lite” versions of the commercial software. These are intended principally for small businesses and enterprises that do not need the complete capabilities of, say, a 3-D modelling system, but must be able to view such documentation and prepare compatible drawings. Again, the “office” environment was a long time not represented in this sector, but has recently started to be available. These will also come with a single or multiple, but limited licence and now mostly be registered with the manufacturer.
3. Free or “open source” software. This is designed for general distribution and has no particular limitations as to use, except that it may not be changed in any way. Naturally, such software has its limitations, but may serve very adequately for many purposes. Practically all types of software are to be found in this category. One notable application distributes the software to read its documents freely, but charges for the software to produce the documents. This policy is arguably the motor behind its ride to a position as industry standard, since you can always be certain that he receiver can decipher whatever is sent, without long discussions about compatibility and versions. Clearly, there can be no piracy of products that fall into the third category, except for changing of the code or reuse of the code for other purposes, but this does not appear to be a major issue at the moment, so we will concentrate our attention on the first two categories.
Both of these categories contain software that is copied and distributed either free of charge or for a nominal fee. Naturally, the full versions of the software are preferred, but the simplified versions are also to be found, depending on what is available.

Types of Software Pirate

This puts our software pirates into two categories of their own:
1. Those who knowingly use a copy of software “borrowed” from work or supplied by friends, who probably acquired it by the same means.
2. Those who prepare copies of software from an original and sell it at a low price through internet auctions or on market stands. Their customers may, in many cases, be unaware that the software has been pirated and simply be pleased to acquire a software package at a bargain price. Some will be quite well aware of the actual source, but still prepared to take this means of saving money.

Composition of the Groups:

So who is to be found in these two groups?
1. This group is very widely ranged and consists of school children, people practicing at home with the company software, various private persons with an interest in computers who will try anything that is free and, possibly, very small businesses. Many schools will supply their students with copies of software licensed for the school to enable them to complete homework or learn to use it for technical subjects. A student finishing a technical school with little or no knowledge of the technical software used in their industry will not easily find employment, so a blind eye is turned in many schools to this practice. Schoolwork is often required to be written on computer these days, and again, this is only really possible if some form of text software is available. Those who use company software at home to play with or for their children to complete homework are also a large group. The computer has become a part of our lifestyle in the western hemisphere, and many people are interested in the possibilities opened by the modern generation of powerful number-crunchers. The days of mainframe computers costing hundreds of thousands of dollars is not gone, but the small computer in a network has taken over in many areas, so the professional software that would earlier have required a mainframe connection and a whole basement full of equipment will now run happily on a home computer. There may be a loss of speed, but who cares? The vast majority of these people know full well that what they are doing is not allowed, but consider this as a very minor matter, and would laugh at any suggestion that they should purchase the software officially. The few companies that also do this are saving money that they probably do not have, despite being aware of the risks.
2. The group of people who copy software and distribute it for sale as being genuine are working simply for profit, taking advantage of the simplicity of the process and the high prices of genuine software. The general public is not aware of the penalties for this type of action and is often unsure about recognising the genuine article. Other items in the consumer market are available from many manufacturers as basically identical products, so why should this not be the case with software? Very many are simply duped into buying what they see as a cheap alternative to a brand-marked product.

Costs of Software Piracy:

So what are the real costs to the software companies?
In most cases, school and college students would not be in a position to pay the costs for the expensive commercial software they use in technical subjects, and the schools and colleges are not in a position to supply this to them free of charge. Most schools have licences for software to be used on the premises, but this is not available for the students at home. Theoretically, they will use the computers at school to complete work and practice, but this is generally not possible due to a lack of resources, or classrooms locked because of vandalism. The only way to solve the problem is for the schools to simply distribute the software to their students on the basis of it being only for their use. There is no licence and no direct upgrade possible. Generally, although illegal, this system works quite well. Schools try to copy upgrades and patches for their students, mostly successfully. The snag to the matter is that we educate people in that this is perfectly acceptable practice, despite it being illegal. No-one would think of insisting or even checking that drop-out students erase the software and no longer use it, but this is probably fairly well assured by the fact that they have dropped out in the first place.

It is very frustrating to see Windows 7 booting extremely slow on a laptop or computer. The same agony is intensified when that happens with a newer laptop. Why Windows 7 freezes on startup and how this problem can be fixed? To find out how, safely perform these tweaks and fix Windows 7 freezing issue:

Cause – 1: Antivirus Behind Win 7 Freezes: Temporarily Uninstall Your Antivirus Program

Although this might take some of your time, but it is important to do this computer maintenance at this stage in order to fix the problem you are facing.

Most of the times due to resource-intensive antivirus programs Windows 7 freezes on startup. These programs not only take too long to load themselves but also make the entire system slow to boot.

You can test this cause only by temporarily removing your antivirus software. Although I would not like to take name of any particular software, but it has been noted that the AVG causes freezing issue due to which Windows 7 starts slow. If, after removing the antivirus software, your computer has started to boot faster and without any freezing, then simply decide to switch to some other anti-virus software.

Cause-2: Registry Errors: Fix Windows 7 Registry With Some Effective Registry Cleaner

The Windows 7 consists of a very important component called Registry which is the key to all programs and services running on your system. The registry component contains immense volume of registry data important to run Windows 7 faster at start as well as throughout the computing process.

If your Windows 7 freezes on startup then it is highly recommended you run an effective scan through a registry cleaner and PC optimizer software. Read definition of Registry at end.

Cause 3: Windows Live ID Services: Can You Afford to Uninstall/Remove these Services?

It has been seen in many PCs that due to the Windows Live ID services, especially starting with the Windows startup cause freezing during the boot process. If you are not a regular user of these services then through Control Panel option in the Windows 7 you can uninstall them easily to fix Windows 7 freezing.

Cause 4: Too Many Startup Programs–Disable Some or All Programs

When your computer starts, there are some softwares installed in your computer which are set/configured to start with the startup process. This puts a load during the boot and a computer running Windows 7 freezes on startup and delays the entire process.

To disable these programs you can press Start > Type Msconfig in Search or Run > Startup > Choose Disable All or Select Services to Disable them individually.

Cause 5: Low RAM Capacity – Consider Upgrading RAM

If you are running Windows 7 on your old system then make it sure it has at least 1 GB RAM space available. However, it is better you upgrade it further to 2 or 4 GB. In case the low capacity of RAM is causing Windows 7 to freeze on startup then you will have to upgrade it in addition to scanning your system registry regularly.

Cause 6: Solid Colors: Do Not Choose the Solid Colors for Desktop Personalztion

Windows 7 has excellent dekstop personalization options available which can be accessed through using the “right-click” option of the mouse on desktop. There is one settings which some users enable to set solid colors for the background picture. If this is the case then it is recommended you choose a simple desktop background image. You can do this in the following way:

Desktop > Mouse Right Click > Personalization > Desktop Background > From Options Unselect the Solid Colors Option.

Cause 7: Aero Themes: Disable if These Themes are Behind Windows 7 Slow Boot

There is one tremendous option in Windows 7 which is called the Aero Themes. Try to disable this option if your Windows 7 freezes on startup. As we know desktop is the first thing that comes up after the boot is completed, there is needed time to load heavy aero themes. Thus disabling these themes might speed up Windows 7 boot time and end freezing issue as well.

Cause 8: Desktop Widgets: Try to Disable These Widgets

As the Windows 7 loads it places all the things in que while it is still booting. What happens is that due to too many startup services, sometime Windows 7 freezes on startup. The desktop widgets such as Clock, Temperatures, etc are also known to cause this freezing issue in the computers.

Cause 9: Super-fetching Disabled? Try to Enable it

In some Windows 7 PCs there occurs freezing in the boot process because the super-fetching option is disabled. You can enable this service to fix this issue in the following way:

Start > Search > Regedit > Now locate this subkey: HLKM\ SYSTEM\CurrentControlSet\ Control\SessionManager\MemoryManagement\ PrefetchParameters.

In the right side, double-click EnablePrefetcher.
Change the value to 2 and click OK.
In the right side, double-click EnableSuperfetch,.
Change the value to 2 and click OK.

Now exit the registry editor and restart your system to let these settings take effect. After using this carefully, it is highly likely you will reduce freezing during Windows 7 startup.

Cause 10: P2P Streaming/Other Suspicious Programs Causing Freeze at Start

It is quite possible that some streaming programs might be causing Windows 7 to freeze during the startup. If that is the case then it is wise to remove such programs.

Cause 11: Outdated Drivers

If your system is quite old then it might have some of the drivers outdated. It is wise to update all your computer drivers to enhance the boot-up process of your computer.

Following these guidelines will hopefully solve your problem. It is recommended you do not miss scanning Windows registry.

Definition of Registry: Registry is the Windows database which stores, in the form of registry keys, information about all the computer programs, softwares and hardwares.
