Testing Spring Boot Eureka Server 404 - spring-boot

Question

I'm trying to test authentication in my Spring Boot Eureka Server. To do so, I perform a GET on /eureka/apps. I get a 404 instead of 200.
#RunWith(SpringRunner.class)
#WebAppConfiguration
#SpringBootTest(classes = Application.class)
public class GlobalSecurityTest {
#Autowired
private WebApplicationContext wac;
#Autowired
private FilterChainProxy springSecurityFilterChain;
private MockMvc mockMvc;
#Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac)
.addFilter(springSecurityFilterChain).build();
}
#Test
public void givenRoleDiscoveryClient_whenGetEureka_then200() throws Exception {
mockMvc.perform(get("/eureka/apps").header(HttpHeaders.AUTHORIZATION, TOKEN_DISCOVERY_CLIENT)
.andExpect(status().isOk());
}
}
Eureka starts correctly as the logs prove:
2018-04-12 23:07:39.308 INFO 80833 --- [ Thread-12] e.s.EurekaServerInitializerConfiguration : Started Eureka Server

java.lang.AssertionError: Status
Expected :200
Actual :404
My security config:
#Configuration
public class WebSecurityConfig {
#Configuration
#Order(3)
public static class DiscoveryClientSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private StateTokenHttpSecurityConfigurer stateTokenHttpSecurityConfigurer;
#Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/eureka/**").authorizeRequests()
.anyRequest().hasRole(Role.DISCOVERY_CLIENT.toString())
.and().exceptionHandling().authenticationEntryPoint(new Http401UnauthorizedEntryPoint());
stateTokenHttpSecurityConfigurer.configure(http);
}
}
}
The Eureka server works fine when I run the application instead of the test.

Don't use MockMvc, because it is limited to testing the web layer, but Eureka mappings aren't registered there. Instead, use TestRestTemplate.
Remove #WebAppConfiguration and add weEnvironment setting in #SpringBootTest
#SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
Autowire TestRestTemplate and local server port
#Autowired
private TestRestTemplate restTemplate;
#LocalServerPort
private int localServerPort;
Perform the request
#Test
public void givenRoleDiscoveryClient_whenGetEurekaPage_then200() throws Exception {
HttpHeaders headers = new HttpHeaders();
headers.set(HttpHeaders.AUTHORIZATION, TOKEN_DISCOVERY_CLIENT);
HttpEntity entity = new HttpEntity<>(null, headers);
String endpoint = "https://localhost:" + localServerPort + "/eureka/apps";
ResponseEntity responseEntity = restTemplate.exchange(endpoint, HttpMethod.GET, entity, String.class);
assertThat(responseEntity.getStatusCode()).isEqualTo(HttpStatus.OK);
}
And off you go.
