Check redirect URL HTTP status code using MockMvc

Question

I want to test the login process of a Spring boot application using MockMvc. After successful login, the user is redirected to / home. To test this, I use:

@Test
public void testLogin() throws Exception {
    RequestBuilder requestBuilder = formLogin().user("[e-mail]").password("test");
    mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().isFound());
}

This test provides the expected results.

In addition, I have to check the HTTP status code of the redirected page (/ home). Assuming the / home page returns an internal HTTP 500 server error, I need to check this.

I tried the following:

@Test
public void testLogin() throws Exception {
    RequestBuilder requestBuilder = formLogin().user("[e-mail]").password("test");
    mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().isFound());
    mockMvc.perform(get("/home").with(csrf())).andExpect(status().isOk());
}

Instead, if you get 200 or 500 (in case of an error), I get a status code of 302.

Is there a way to correctly check the HTTP status code when using a redirect URL?

Thanks and best regards

-, 2 , 2 :

@Test
public void testSuccessfulLogin() throws Exception {
    RequestBuilder requestBuilder = formLogin().user("[e-mail]").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("[e-mail]").password("test");
    mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().is5xxServerError());
}

    @MockBean

@Test
public void testHomepageThrows500() throws Exception {

    given(yourService.someMethod()).willThrow(new Exception("something bad happened");

    RequestBuilder requestBuilder = formLogin().user("[e-mail]").password("test");
    mockMvc.perform(requestBuilder).andExpect(redirectedUrl("/home")).andExpect(status().is5xxServerError());
