: Ensuring that different software modules work together effectively.
: Final verification (often by the user) to determine if the system is ready for deployment.

Testing typically occurs in hierarchical stages to catch errors as early as possible:
: A flaw in the software that causes it to deviate from its expected behavior. Levels of Testing : Ensuring that different software modules work together
: Validating the smallest testable components (functions or classes) in isolation.
: Testing the complete, integrated system to verify end-to-end performance and functionality. Software Testing
: A detailed set of conditions, steps, and expected results used to validate a specific functionality.
