RESILIENT MOCK OBJECT CREATION FOR UNIT TESTING

Embodiments of the invention provide for fault alerting in mock object supported unit testing. In a method for fault alerting in mock object supported unit testing an instance a mock object proxying for an object under test by test code is created in memory of a computing system and an invocation of a method in the object under test is proxied by method name to the mock object. Then, it is determined whether or not a method exists in memory for the mock object corresponding to the method name. Finally, an exception handler is invoked for the mock object outputting error text indicating a non-presence of a method associated with the method name responsive to a method by the method name not existing in the memory for the mock object, but otherwise a method is invoked that exists in the memory of the mock object corresponding to the method name.
