TDD newbie

[kantorn]

Hi all

I'm currently exploring the recommended "test first" approach in Spring development, and I must admit I'm fascinated by all the possibilities theis method has.

But I'm also a newbie in this way of thinking, and have run into problems

I wonder why

private MockControl control = null;
    private LogicFacade mockLogic = null;
    private DateSearchFormController datefc = null;
    private MockHttpServletRequest mockreq = null;
    

    protected void setUp() throws Exception {
        control = MockControl.createControl(LogicFacade.class);
        mockLogic = (LogicFacade) control.getMock();
        datefc = new DateSearchFormController();
        datefc.setLogic(mockLogic);
        mockreq = new MockHttpServletRequest();
    }
    
    protected void tearDown() throws Exception {
        control = null;
        mockLogic = null;
        datefc = null;
        mockreq = null;
    }
    
    public void testLoginCheck() throws Exception {
    	MockHttpSession mockSession = new MockHttpSession();
    	MockControl sessionControl = MockControl.createControl(UserSession.class);
    	UserSession session = (UserSession) sessionControl.getMock();
    	
    	AvikUser user = new AvikUser();
    	user.setRole(AvikRole.POWERUSER);
    	session.setUser(user);
    	
    	mockSession.setAttribute("usersession", session);
    	mockreq.setAttribute("something", new Object());
    	mockreq.setSession(mockSession);
    	datefc.handleRequest( mockreq , new MockHttpServletResponse() );
    	
    }

generates the following exception

    [junit] Testcase: testLoginCheck(ks.rah.avik2.test.TestSearchController):   Caused an ERROR

testing this code

protected ModelAndView onSubmit(HttpServletRequest request, 
									HttpServletResponse response,
									Object command, 
									BindException errors) throws Exception {
		DateSearchForm form = (DateSearchForm) command;
		AvikUser user = AvikController.checkLoggedIn(request, AvikRole.POWERUSER, false);
.
.
.

Seems like the MockHttpServletRequest/Response is null somehow.....

Anybody have an idea?

You are using the constructor for MockHttpServletRequest which does not specify any 'method' string ('GET' or 'POST'), so you need to set this yourself manually as a property.

That did it.

Thanks!
