systemprüfungen

Systemprüfungen, also known as system tests, are a crucial phase in the software development lifecycle. They are conducted after integration testing and before acceptance testing. The primary goal of system testing is to evaluate the complete and integrated software system against specified requirements. This means verifying that all components of the system work together as intended and that the system as a whole meets the business and user needs.

During system testing, the focus shifts from individual modules to the entire system's functionality, performance, security, and reliability. Testers execute end-to-end scenarios that mimic real-world usage. This helps uncover defects that might arise from the interaction between different modules or from external system dependencies. Common types of system tests include functional testing, performance testing, security testing, usability testing, and recovery testing.

The objectives of system testing are to ensure that the system is stable, performs according to expectations, and is ready for user acceptance testing. It identifies any discrepancies between the expected and actual behavior of the system, providing valuable feedback to the development team for further refinement. Successful system testing significantly reduces the risk of releasing a faulty product and increases customer satisfaction. It is a vital step in delivering a high-quality software product that meets all functional and non-functional requirements.
