Software Testing Lifecycle
The Software Testing Lifecycle (STLC) is a systematic process that defines a sequence of activities for testing software applications to ensure quality and reliability. It consists of distinct phases, from requirement analysis to test closure, each with specific objectives and deliverables. STLC is integrated within the broader Software Development Lifecycle (SDLC) to align testing efforts with development stages.
Developers should learn STLC to implement structured testing practices that catch defects early, reduce rework costs, and deliver high-quality software. It is essential in agile and waterfall projects for creating test plans, executing tests systematically, and ensuring compliance with requirements. Use cases include developing complex applications, maintaining legacy systems, and adhering to industry standards like ISO/IEC/IEEE 29119.
