为什么我的单元测试在我尝试呈现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 HomePage 上的登录是否有效，如果有效则呈现 SuccessPage但它给了我一个 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 wicket:id="error" 并通过了测试 :D
