Unittesting secured rest controller with spring - spring

Question

I have a very small REST application written using spring boot.
I want to write a unit test for the authentication, but even if i add #MockWithUser to a test, i receive a 401 error.
The importent files are
the security configuration
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
.antMatchers("/**")
.hasRole("USER")
.anyRequest()
.permitAll()
.and()
.anonymous().disable()
.exceptionHandling()
.authenticationEntryPoint(new org.springframework.boot.autoconfigure.security.Http401AuthenticationEntryPoint("headerValue"));
}
The MainApp with a controller
#Controller
#RequestMapping("/test")
#ComponentScan
#SpringBootApplication
public class MainApp {
#RequestMapping(method= RequestMethod.GET)
public #ResponseBody String sample(){
return "Test";
}
public static void main(String[] args) throws Exception {
SpringApplication.run(MainApp.class, args);
}
}
And finally the test (which is not working)
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest(classes = MainApp.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class AuthenticationTest {
#Autowired
private TestRestTemplate testRestTemplate;
#Autowired
private WebApplicationContext context;
#Autowired
private Filter springSecurityFilterChain;
private MockMvc mvc;
#LocalServerPort
private int port;
#Before
public void setup() {
mvc = MockMvcBuilders
.webAppContextSetup(context)
.addFilters(springSecurityFilterChain)
.build();
}
#Test
#WithMockUser(username="admin",roles={"USER","ADMIN"})
public void shouldReturn200WhenSendingRequestToControllerWithRoleUser() throws Exception {
then(SecurityContextHolder.getContext().getAuthentication().isAuthenticated());
mvc.perform(get("/test")).andExpect(status().isOk());
}
#Test
#WithMockUser(username="admin",roles={"USER","ADMIN"})
public void shouldAuthenticatedBeTrueWithRoleUser() throws Exception {
then(SecurityContextHolder.getContext().getAuthentication().isAuthenticated());
}
}
As you can see, there are two test cases. The second is passed, the first is not (receiving 401, not 200 as response code, stacktrace below).
Can you tell me how an can test authentication properly?

Answer 1

Simply using addFilters is not going to be sufficient to build the security context. Here are a couple solutions:
In your setup method replace
.addFilters(springSecurityFilterChain)
with
.apply(springSecurity())
from
org.springframework.security.test.web.servlet.setup.SecurityMockMvcConfigurers.springSecurity;
That alone should resolve the test failures. This still leaves you with a nasty looking class that can be cleaned up quite a lot with the use of WebMvcTest. Here is a more succinct version of your test, using WebMvcTest.
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
#RunWith(SpringRunner.class)
#WebMvcTest(controllers = MainApp.class)
public class AuthenticationTest {
#Autowired
private MockMvc mockMvc;
#Test
#WithMockUser(username = "admin", roles = {"USER", "ADMIN"})
public void shouldReturn200WhenSendingRequestToControllerWithRoleUser() throws Exception {
mockMvc.perform(get("/test")).andExpect(status().isOk());
}
}
