Businesses involved in software should always make sure that their software product is free of bugs, and almost there are errors or any kind of risks which cause problems to their customers(end-users), should be fixed before releasing the product to the market. Even though it is not possible to deliver 100% bug-free software product, software businesses should ensure that their product is almost free of all possible bugs/errors. To do so, they should follow software testing procedures or any kind of other testings from start to end of software development.
Software developing industry is very competitive industry to do business with. There are many software products compete in the market for a particular problem/need of customers. For an example, there are various software products like SAP, Tally and etc are competing in accountancy filed. So, it is very important that the software which you produce is very reliable, user-friendly, functional, secure and etc. Specially if a software provides solutions to business functions like accounting, it has to be very secure, specially from cracking, hacking and virus attacks to end-users' data. To do so security of the product should be tested well during process of software testing.
Usually there are software firms run out of time for extended testing due to tight deadline and/or delays on earlier software development phases. It leads to release the software with bugs/errors, which in return gains poor reputation to the brand. To overcome such things, software testing should not be omitted/ignored/shortened. Overall Software testing cycle should be followed. Alpha testing, beta testing, verification & validations too have to be considered during software testing process.
Unit testing should be carried out to ensure each unit of the software, operates correctly. Apart form that when the units are integrated, integration testing should be carried out to ensure software units continue working properly when those are integrated. Assuming that integrated software will work fine because of unit testing is carried out and all units are working well, there are cases where integrated software fail to work well, so integration testing is the must.
Software should perform what is supposed to perform in other words, software should perform as what stated in software development specification which is filtered out/translated from customer requirements. To test this performance testing should be carried out.
Functionality of the software also important to compete in high competitive software industry. Each functions should work properly, individually as well as when those are integrated. Functional testing should be done to do so.
Regression testing also important when some reported issues are fixed. Other than that compatibility and usability testing should be performed before final release of the software product.
Beta version of software can be distributed to other/existing customers, which allow customers to work on it and report any issues. It helps to find out errors/bugs under different environment.
Finally even software testing
is time consuming process. It is very essential to deliver quality and error free software product which in turn gives more high brand reputation and more businesses in near future.
