The software testing life cycle consists of various testing activities that need to be carried out to validate if the software meets the required design specification. It also explains which testing activity needs to be carried out and when. The different phases of the software testing process have been explained in this article. The software testing life cycle consists of a series of stages through which a software product goes through and describes the various activities pertaining to testing that are carried out on the product. Here's an explanation of the STLC along with a flowchart. In every organization testing is an important phase in the development of a software product. However, the way it is carried out differs from one organization to another. It is advisable to carry out the testing process from the initial stages, with regard to the Software Development Life Cycle or SDLC to avoid any complications. Requirement Stage.This is the initial stage of the software testing process. In this phase the developers take part in analyzing the requirements for designing a product. The role of software testers is also necessary in this phase as they can think from the 'users' point of view which the developers may not. Thus a team of developers, testers and users can be formed, to analyze the requirements of the product. Formal meetings of the team can be held in order to document the requirements which can further be used as software requirements specification or SRS.
