Software testing is the most crucial aspect of the Software Development Life Cycle (SDLC). It is crucial because it helps in finding out and fixing bugs or any major hidden issues that software might have.
For the systematic testing of a software product, it has to undergo sequences of activities which are performed during the testing process, called Software Testing Life Cycle (STLC). Testing helps improve the quality of the software product that is built with specific business requirements and goals that it is expected to perform. Nothing annoys customers more than a bug-filled user experience. Therefore, today testing is not only about reporting bugs to the developer. It has a wide role to play and is a mandatory phase to execute from the initial phases of a project. Software testing is done in phases.
