为什么我的单元测试在尝试渲染另一个页面时给我一个AssertionFailedError

Question

我正在学习单元测试，并尝试检查登录名在HomePage上是否有效，并且是否可以显示SuccessPage，但它给了我AssertionFailedError

。java：

    @Test
    public void validLogin(){
        tester.startPage(HomePage.class);

        FormTester form = tester.newFormTester("userForm");
        form.setValue("username", "emile");
        form.setValue("password", "123");
        form.submit();
        //onsubmit the Successpage is rendered in response
        tester.assertRenderedPage(SuccessPage.class);

    }

错误：

Answer 1

我得到了答案，所以我没有将form.submit();引用到onSubmit()函数，所以我基本上是这样做的：

@Test
    public void validLogin() throws Exception {
        tester.startPage(HomePage.class);

    //  tester.startComponentInPage(HomePage.class);
        FormTester form = tester.newFormTester("userForm");
        form.setValue("username", "emile");
        form.setValue("password", "123");
        form.submit("error"); // new code that was edited
        //onsubmit the Successpage is rendered in response
        tester.assertRenderedPage(SuccessPage.class);


    }

form.submit("error");现在引用了wicket:id="error"，并通过了测试：D
