Junit and EasyMock Servlet testing

I have a problem with testing Servlet. Bouncer is a Servlet with simple method doPost and init overrited by me. But when i run that code i get exception

@Before
        public void Before() throws IOException, ServletException,
                InstantiationException, IllegalAccessException,
                IllegalArgumentException, InvocationTargetException,
                NoSuchMethodException, SecurityException, ClassNotFoundException {
            encoder = EasyMock.createMock(Encoder.class);
            EasyMock.expect(encoder.encode("password")).andReturn("asdf");
            EasyMock.expect(encoder.encode("nic")).andReturn("asss");
            EasyMock.expect(encoder.encode("Password")).andReturn("ass");
            EasyMock.replay(encoder);
            db = EasyMock.createMock(UserDataBase.class);
            db.connect();
            EasyMock.expect(db.isConnected()).andReturn(true);
            EasyMock.expect(db.getUserByLoginAndPassword("login", "asss"))
                    .andReturn(null);
            EasyMock.expect(db.getUserByLoginAndPassword("login", "asdf"))
                    .andReturn(new User("Rafal", "Machnik"));
            EasyMock.expect(db.getUserByLoginAndPassword("fake", "asdf"))
                    .andReturn(null);
            EasyMock.expect(db.getUserByLoginAndPassword("login", "ass"))
                    .andReturn(null);
            EasyMock.replay(db);

            lsf = EasyMock.createMock(LoginServiceFactory.class);
            EasyMock.expect(lsf.getEncoder()).andReturn(encoder).anyTimes();
            EasyMock.expect(lsf.getUserDataBase()).andReturn(db).anyTimes();
            EasyMock.replay(lsf);

            config = EasyMock.createMock(ServletConfig.class);
            EasyMock.expect(config.getInitParameter("LoginServiceFactory"))
                    .andReturn("pl.to.cw4.LoginServiceFactory");
            EasyMock.replay(config);

            request = EasyMock.createMock(HttpServletRequest.class);
            EasyMock.expect(request.getParameter("login")).andReturn("login")
                    .anyTimes();
            EasyMock.expect(request.getParameter("password")).andReturn("password")
                    .anyTimes();
            EasyMock.replay(request);

            pageSource = new StringWriter();

            response = EasyMock.createMock(HttpServletResponse.class);
            EasyMock.expect(response.getWriter())
                    .andReturn(new PrintWriter(pageSource)).anyTimes();
            EasyMock.replay(response);

            bouncer = new Bouncer(lsf);

            bouncer.init(config);

        }

        @Test
        public void bouncerTest() throws ServletException, IOException {
            bouncer.service(request, response);
            assertNotNull(pageSource.toString());

        }

java.lang.AssertionError: Unexpected method call getMethod(): at org.easymock.internal.MockInvocationHandler.invoke(MockInvocationHandler.java:32)...

If someone had idea how to fix it I will be thankful.

The error indicates that the easymock has come across a method call getMethod() in a mocked object . Debug the program line by line and add a expect call for the mocked object.

You don't have to add the method call in expect if it not a mocked object but all the calls in a mocked object should be added to your test method.

getMethod() is called in the service and since you are mocking HttpServletRequest , you also need to mock all the methods call on HttpServletRequest

The service() method calls getMethod() on the request to determine if it must call doGet(), doPost() or the other servlet methods. Since you didn't stub this call to getMethod() on your mock request, EasyMock throws this exception.

Why don't you call doPost() directly, rather than calling service(), since that's the method you want to test?
