System testing is a type of software testing that verifies that a complete and integrated software system meets specified requirements and behaves as expected. System testing is typically performed after unit testing and integration testing and it validates the entire system, including its interactions with external systems and its end-to-end functionality.
System testing typically covers a wide range of scenarios and test cases, including functional testing, performance testing, security testing, and compatibility testing. The goal of system testing is to catch any issues or defects that may have been missed in previous testing phases and to ensure that the system behaves as expected from the end-user's perspective.
System testing is an important step in the software development process, as it helps to validate that the system meets the required functional and non-functional specifications, and that it is ready for release to the production environment.
