A system and method for requirement driven interoperability/compliance testing of Hardware and Software in a distributed environment. Three modules are configured as a default system: a test definition, a SUT definition and a test result. A series of tree elements are coupled to represent requirements to test case mapping. Test cases are executed and components in the system are assigned with test results while requirements coverage is computed. Auto-detection of additional parts and test cases enables validity checking of the requirement to test case tree and reports are generated.
