Starting from the classic Waterfall Software Development Life Cycle (SDLC) model to the modern Agile-based SDLC, testing forms one of the most important sections of any development process. After the development phase is complete, the application is sent for testing. Every application, irrespective of its volume or size, is thoroughly tested before it is released for production. Testing software is so important that no software can ever be successful without going through this phase. Large enterprises keep separate teams that dedicatedly test applications and frameworks before finalizing the release. The purpose of these testing teams is to find out hidden flaws/bugs in the software, which might have been produced because of some wrong or illegal input that has not been taken care of by the developers during the phase of development. Most of these bugs come from the validation of code blocks or even...
