This standard defines a methodology to evaluate the test scenarios and provides a procedure extending test scenarios to test cases for a given function in a traceable way based on the testability. This standard also defines necessary characteristics of a test case that include but not limited to test initialization, test stimulation, test steps, pass/fail-criteria and expected results etc. This standard describes evaluation methods and criteria that include but not limited to the relation between the test case, real world as well as databases/information-sources, e.g. frequency, criticality, complexity, and the relation between the test scenario and the tested function, e.g. coverage of ODD. The contents are intended to be applied to Level 3 and higher ADS defined in ISO/SAE 22736.
