Spring Test returning 401 for unsecured URLs

I found the answer
Spring docs says that:

@WebMvcTest will auto-configure the Spring MVC infrastructure and
limit scanned beans to @Controller, @ControllerAdvice, @JsonComponent,
Filter, WebMvcConfigurer and HandlerMethodArgumentResolver. Regular
@Component beans will not be scanned when using this annotation.

And according to this issue in github:

https://github.com/spring-projects/spring-boot/issues/5476

The @WebMvcTest by default auto configure spring security if spring-security-test is present in the class path (which in my case is).

So since WebSecurityConfigurer classes aren’t picked, the default security was being auto configured, that is the motive I was receiving the 401 in url’s that was not secured in my security configuration. Spring security default auto configuration protects all url’s with basic authentication.

What I did to solve the problem was to annotate the class with @ContextConfiguration, and @MockBean like it is described in the documentation:

Often @WebMvcTest will be limited to a single controller and used in
combination with @MockBean to provide mock implementations for
required collaborators.

And here is the test class

@RunWith(SpringRunner.class)
@WebMvcTest
@ContextConfiguration(classes={Application.class, MvcConfig.class, SecurityConfig.class})
public class ITIndex {

    @Autowired
    WebApplicationContext context;

    MockMvc mockMvc;

    @MockBean
    UserRegistrationApplicationService userRegistrationApplicationService;

    @MockBean
    UserDetailsService userDetailsService;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders
                        .webAppContextSetup(context)
                        .apply(springSecurity())
                        .build();
    }

    @Test
    public void should_render_index() throws Exception {
        mockMvc.perform(get("https://stackoverflow.com/"))
            .andExpect(status().isOk())
            .andExpect(view().name("index"))
            .andExpect(content().string(containsString("Login")));
    }
}

Application, MvcConfig and SecurityConfig are all my configuration classes
