The implementation is straightforward: The method eqException must create the argument matcher with the given Throwable, report it to EasyMock via the static method reportMatcher(IArgumentMatcher matcher), and return a value so that it may be used inside the call (typically 0, null or false). For eg: if the following expectation is set in test code. 'capture' just to test one method but I have separate tests for the method Since EasyMock 3.0, EasyMock can perform class mocking directly without EasyMock framework creates the mock objects using the java.lang.reflect.Proxy object.
