Test HTTP status code of redirected URL with MockMvc
提问by Ben
I want to test the login process in a Spring Boot Application using MockMvc. After the successful login, the user gets redirected to /home. To test this, I use:
我想使用 MockMvc 在 Spring Boot 应用程序中测试登录过程。成功登录后，用户将被重定向到 /home。为了测试这一点，我使用：
@Test
public void testLogin() throws Exception {
RequestBuilder requestBuilder = formLogin().user("[email protected]").password("test");
mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().isFound());
}
This test delivers the expected results.
该测试提供了预期的结果。
In addition, I must test the HTTP status code of the redirected page (/home). Lets say the /home-page returns an HTTP 500 internal Server error, I need to be able to test this.
另外，我必须测试重定向页面（/home）的HTTP状态码。假设 /home-page 返回 HTTP 500 内部服务器错误，我需要能够对此进行测试。
I tried the following:
我尝试了以下方法：
@Test
public void testLogin() throws Exception {
RequestBuilder requestBuilder = formLogin().user("[email protected]").password("test");
mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().isFound());
mockMvc.perform(get("/home").with(csrf())).andExpect(status().isOk());
}
Instead if getting a 200 or a 500 (in case of an error), I get the status code 302.
相反，如果得到 200 或 500（在出现错误的情况下），我会得到状态代码 302。
Is there any way to correctly test the HTTP status code when following a redirect-URL?
在跟踪重定向 URL 时，是否有任何方法可以正确测试 HTTP 状态代码？
Thanks and best regards

First, I would split your test into 2 separate tests, because you are testing 2 quite different scenarios:
首先，我会将您的测试分成 2 个单独的测试，因为您正在测试 2 个完全不同的场景：
@Test
public void testSuccessfulLogin() throws Exception {
RequestBuilder requestBuilder = formLogin().user("[email protected]").password("test");
mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().isFound());
}
@Test
public void testHomepageThrows500() throws Exception {
// configure a mock service in the controller to throw an exception
RequestBuilder requestBuilder = formLogin().user("[email protected]").password("test");
mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().is5xxServerError());
}
Your first test is that of the successful login scenario.
您的第一个测试是成功登录场景。
The second test, as you've worded it in your question, is that where the home page (assuming a controller) returns a HTTP 500.
To get to the home page, you still need to login - it's not the act of logging on that generates the error, its the controller itself once you've logged on.
To make the controller return a HTTP 500 you are going to need to simulate some error. Without seeing your controller, I can only guess there is some service that is injected in. In your test you should be able to provide a mock of that, and then configure the mock to throw an exception.
第二个测试，正如您在问题中所说的，是主页（假设有控制器）返回 HTTP 500 的地方。
要进入主页，您仍然需要登录 - 这不是登录的行为一旦您登录，就会产生错误，它是控制器本身。
要使控制器返回 HTTP 500，您需要模拟一些错误。在没有看到您的控制器的情况下，我只能猜测注入了一些服务。在您的测试中，您应该能够提供一个模拟，然后配置模拟以抛出异常。
You should be able to inject a mock something like this:
你应该能够注入这样的模拟：
@RunWith(SpringJUnit4ClassRunner.class)
@WebMvcTest(HomeController.class)
public class HomeControllerIntegrationTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private YourService yourService;
And then within your test do something like the following (I'm using the BDD methods of mockito):
然后在您的测试中执行以下操作（我使用的是 mockito 的 BDD 方法）：
@Test
public void testHomepageThrows500() throws Exception {
given(yourService.someMethod()).willThrow(new Exception("something bad happened");
RequestBuilder requestBuilder = formLogin().user("[email protected]").password("test");
mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().is5xxServerError());
}
