System Tests are a type of software testing that evaluates the complete and integrated software application. The goal is to ensure that the system meets specified requirements and functions correctly in a real-world environment. This testing phase typically occurs after unit and integration tests, focusing on the overall behavior of the system. During System Tests, various scenarios are executed to verify that all components work together as intended. Testers check for issues related to performance, security, and usability, ensuring that the software is reliable and user-friendly before it is released to end-users.
