Base Unit Test for Controllers?

[ryan.tyer]

Is there a base class that I should be using for testing controllers (looking in org.springframework.test but I'm not seeing anything geared towards controller testing) or should I be writing my own using XmlWebApplicationContext or some such context? Any other tips pertaining to controller testing would be appreciated, as well.

Thanks,

Ryan

Take a look at MockHttpServletRequest and MockHttpServletResponse in spring-mock.jar

There are a few options for testing. For integration tests, you can use AbstractDependencyInjectionSpringContextTests.

To test a smaller scope which is often pereferable, you can insert mocks (e.g. using EasyMock) for your services layer.

Here's an incomplete mock example:

        //Add request data
        request = new MockHttpServletRequest("POST", "/");
        response = new MockHttpServletResponse();

        request.addParameter("formInputName", "formValue");
        ...

        //MockControl.createControl(MyService.class); in setUp
        //Add mock behaviour
        ....
        mc.setThrowable(new DuplicateException("mock"));
        mc.replay();

        //Now test controller
        ModelAndView mv = myController.handleRequest(request, response);
        BindException errors = (BindException) mv.getModel().get(BindException.ERROR_KEY_PREFIX+"command");
        
        assertNotNull(errors);

And don't forget mc.verify() in your teardown.
