Test case data is received for individual test cases. The test case data includes sets of test case specific elements. A test case base object is generated to represent a generic test case. The test case base object includes a set of test case specific properties. The test case base object is expanded into individual test case specific objects that represent the individual test cases. Each individual test case specific object is generated by setting the set of test case specific properties to a respective set of test case specific values as indicated in the sets of test case specific elements. The individual test case objects are used to execute the individual test cases against one or more systems under test.
