What is the primary goal of system testing?

The primary goal of system testing is to validate the complete and integrated software system. This stage of testing occurs after integration testing, where individual modules or components have been combined. System testing assesses whether the entire application meets the specified requirements and works as intended in a real-world environment.

During system testing, the entire system is examined as a whole to ensure that all functionalities operate together without issues. This testing includes verifying both functional and non-functional requirements, such as performance, security, and usability. By executing test cases derived from the overall system specifications, testers can identify any discrepancies between the expected behavior of the system and its actual performance.

Looking at the other options, checking the performance of individual modules pertains to unit testing or integration testing rather than system testing. While enhancing documentation quality is important for overall project success, it is not the main focus of system testing. Evaluating user satisfaction is typically part of user acceptance testing, which occurs after system testing, where end-users interact with the application to validate that it meets their needs.
