Conclusion

The requirements and challenges on test environments of HIL system tests, SW system tests, integration tests and unit tests are widely the same

Corresponding test concepts are applicable to all kind of tests

Vector strategy: provide a comprehensive test solution for all kind of tests based on well established tools

Combine the strength of vTESTstudio and CANoe for system tests with the strength of VectorCAST for code based tests
