java - Junit 和 EasyMock Servlet 测试

Question

我在测试 Servlet 时遇到问题。 Bouncer 是一个带有简单方法 doPost 和 init 的 Servlet，被我重写了。但是当我运行该代码时，我遇到异常

@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: 意外的方法调用 getMethod(): 在 org.easymock.internal.MockInitationHandler.invoke(MockInitationHandler.java:32)...

如果有人知道如何解决它，我将不胜感激。

该错误表明 easymock 在模拟对象中遇到了方法调用 getMethod() 。逐行调试程序并添加对模拟对象的期望调用。

如果它不是模拟对象，则不必在 Expect 中添加方法调用，但模拟对象中的所有调用都应添加到您的测试方法中。

在服务中调用 getMethod() ，并且由于您正在模拟 HttpServletRequest ，因此还需要模拟 HttpServletRequest 上的所有方法调用
