Testing typically occurs in hierarchical stages to catch errors as early as possible: 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). It is a critical phase of the that
: Final verification (often by the user) to determine if the system is ready for deployment. while validation asks
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
: A flaw in the software that causes it to deviate from its expected behavior. Levels of Testing
: Testing the complete, integrated system to verify end-to-end performance and functionality.
