testing form controller

[shoa]

Hello

For Controllers that extend Controller class, I can test the handleRequest function such as:

public void testHandleRequest throws ServerException.....


What will I have to do to test with the classes that extend the SimpleFormController. I think that I donot have to test ffor functions like onSubmit, onBackingObject.....). For example, I have in my form

public ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors){
MyObject myObject = (MyObject)command;
myObjectManager.add(myObject);
return new ModelAndView(new RedirectView(getSuccessView()));
}

How I can test this

Thank you for any help

You should only test *your* code. If you have overridden any of those methods, sure, test them, but don't bother testing Spring's code .

In the same token, you shouldn't really be testing the workflow of a class, just it's individual methods.

For example, I have in my form

public ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors){
MyObject myObject = (MyObject)command;
myObjectManager.add(myObject);
return new ModelAndView(new RedirectView(getSuccessView()));
}

Simply test the method in isolation:

  MyObject myCommand = new MyObject();

  MyController controller = new MyController();

  ModelAndView mav = controller.onSubmit(myCommand);
  View view = mav.getView();
  assertTrue("view is type redirect", RedirectView.class, view.getClass());
  etc.

Note I am using the onSubmit(Object) method, not your method which takes in all the parameters. If you do want to test that, then you can create MockHttpServletRequest and MockHttpServletResponse etc.

Remember, it is much better to have lots of little tests that a single aspect...
