A test services provider is an object that is arranged to provide a standardized interface for calling test harness provided functionality. The test services provider is not tied to a specific test harness, and provides a standard interface such that both test harness functionality and test cases can be written without beforehand knowledge of the other. In operation, the test harness registers the test services that provides with the test service provider, and the test cases retrieve the registered test services from the test harness as needed. Accordingly, the test case does not have to query the test harness itself for the object that provides the desired test harness functionality, but rather uses a standardized interface provided by the test services provider to retrieve the desired test services.
