never mind, i tinkered a little bit and read the API docs. if anyone
is interested, here's what i did.
ActionProxy proxy = getActionProxy("/dummy-action");
MyAction action = (MyAction)proxy.getAction();
MockHttpServletResponse response = new MockHttpServletResponse();
action.setServletResponse(response);
String result = action.dummyAction();
Assert.assertNull(result); //should always be null
String json = response.getContentAsString();
Assert.assertNotNull(json); //shouldn't be null
