I am testing a servlet's doPost() method using EasyMock objects for the HttpServletRequest and HttpServletResponse arguments. Within the doPost() method I'm testing the request and response objects are used as arguments to a static method class for another class, and I want to disregard (i.e. not record as expected) any calls made on the request and response objects within this method call (it's not relevant to this test anyway). For example the doPost() method of the servlet class I'm testing looks like this:
@Override
protected void doPost(final HttpServletRequest servletRequest,
final HttpServletResponse servletResponse)
throws ServletException, IOException
{
// handle an "updateFolder" event
String eventParameter = servletRequest.getParameter("event");
if ("updateFolder".equalsIgnoreCase(eventParameter))
{
// update the news documents folder settings
String folderId = servletRequest.getParameter("folderId");
IPortletContext portletContext = PortletContextFactory.createPortletContext(servletRequest, servletResponse);
IPortletResponse portletResponse = portletContext.getResponse();
portletResponse.setSettingValue(SettingType.CommunityPortlet, "NEWS_DOCUMENTS_FOLDER_ID", folderId);
}
// redirect to the appropriate URL
servletResponse.sendRedirect(redirectUrl);
}
When the above code gets to the step where PortletContextFactory.createPortletContext() is called I don't really care what method calls are made on the request and response objects within that method, but if I pass in mock request and response objects when testing this method I get errors from EasyMock telling me that there are missing behavior definitions. For example I have a test method which looks like this:
@Test
public void testPostWithUpdate()
throws Exception
{
// create mock objects and record their expected calls
HttpServletRequest mockServletRequest = createMock(HttpServletRequest.class);
HttpServletResponse mockServletResponse = createMock(HttpServletResponse.class);
IPortletResponse mockPortletResponse = createMock(IPortletResponse.class);
IPortletContext mockPortletContext = createMock(IPortletContext.class);
expect(mockServletRequest.getContextPath()).andReturn(null);
expect(mockServletRequest.getParameter("event")).andReturn("updateFolder");
expect(mockServletRequest.getParameter("folderId")).andReturn(null);
expect(PortletContextFactory.createPortletContext(mockServletRequest, mockServletResponse)).andReturn(mockPortletContext);
expect(mockPortletContext.getResponse()).andReturn(mockPortletResponse);
mockPortletResponse.setSettingValue(SettingType.CommunityPortlet, "NEWS_DOCUMENTS_FOLDER_ID", null);
mockServletResponse.sendRedirect(EasyMock.anyObject(String.class));
// take the mock objects out of record state
replay(mockPortletContext, mockPortletResponse, mockServletRequest, mockServletResponse);
// instantiate an object of the class and run the method we want to test
ControllerServlet controllerServlet = new ControllerServlet();
controllerServlet.doPost(mockServletRequest, mockServletResponse);
// verify that our mocks behaved as expected
verify(mockPortletContext, mockPortletResponse, mockServletRequest, mockServletResponse);
}
I get the following error when I run the test class:

I assume that the errors above are caused by not recording the method calls executed within the PortletContextFactory.createPortletContext() method on the mock request and response objects passed in as arguments. If this is actually what's happening here then how can I rework things so that the method calls made on the request and response mocks by the PortletContextFactory.createPortletContext() method are disregarded?
Thanks in advance for any suggestions.
