Software testing is the systematic process of evaluating an application to ensure it meets requirements and functions correctly by identifying bugs or missing features . It is a critical phase of the that aims to reduce the risk of failure in operation. Core Concepts and Definitions Software Testing
: Verification asks, "Are we building the product right?" (checking against specifications), while validation asks, "Are we building the right product?" (ensuring it meets user needs). : Final verification (often by the user) to
: Final verification (often by the user) to determine if the system is ready for deployment. while validation asks
Testing typically occurs in hierarchical stages to catch errors as early as possible:
: Testing the complete, integrated system to verify end-to-end performance and functionality.
: Validating the smallest testable components (functions or classes) in isolation.
