: Validating the smallest testable components (functions or classes) in isolation. Software Testing

Testing typically occurs in hierarchical stages to catch errors as early as possible:

: A detailed set of conditions, steps, and expected results used to validate a specific functionality. Software testing is the systematic process of evaluating

: Final verification (often by the user) to determine if the system is ready for deployment.

: A flaw in the software that causes it to deviate from its expected behavior. Levels of Testing Testing typically occurs in hierarchical stages to catch

: 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).
