C:\EasyMock_WORKSPACE>java TestRunner. C:\EasyMock_WORKSPACE>javac CalculatorService.java MathApplication.java MathApplicationTester.java TestRunner.java Now run the Test Runner to see the result: C:\EasyMock_WORKSPACE>java TestRunner Verify the output. Since we don't have a mock object, use PowerMock.replayAll () to finalize the setup. Creates a mock object that implements the given interface, order checking is disabled by default.
