One embodiment of the present invention provides a system that facilitates testing object-oriented programming (OOP) methods. During operation, the system receives a request from a client at a test-automation framework to execute a test case for the OOP methods. In response to the request, the system executes the test case in the test-automation framework. (Note that in this system, a class that includes the OOP methods inherits from an originally intended parent class, and calls to a test class are made via reflection.) The system then determines an outcome of executing the test case. Finally, the system reports the outcome of executing the test case.
