Järjestelmätestausvaiheita

Järjestelmätestausvaiheita refers to the stages of system testing in software development. This crucial phase validates the complete, integrated system to ensure it meets specified requirements. It's typically performed after integration testing and before user acceptance testing.

The initial stage often involves system verification, where the entire system is tested against the functional and non-functional requirements defined in the specifications. This includes checking that all components work together as intended and that the system performs adequately under various conditions. Performance testing, security testing, and stress testing are common activities within this stage to assess the system's robustness, efficiency, and resilience.

Following verification, system testing often moves to system validation. Here, the focus shifts to ensuring the system meets the end-user's needs and expectations. This might involve simulating real-world scenarios and user workflows to confirm the system is fit for purpose and delivers the intended business value. Defects found during these stages are documented, reported, and then addressed by the development team, followed by re-testing to confirm the fixes. The successful completion of all system testing stages is a prerequisite for proceeding to the next phase of the software development lifecycle.
