Run spring boot integration test using maven test but the embeded tomcat is not started

Question

I write an integration test for my spring boot application, it is shown as following code. It works fine in Eclipse IDE by run as Junit test and the embeded tomcat is started and shutdown automatically. But when I run it using maven install, it failed just because the embeded tomcat is not started. Should I need more configuration in Maven? How to do it?

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestCoreConfig.class)
@WebAppConfiguration
@IntegrationTest
public class UserRegistrationTest {

@Autowired
private Receiver receiver;


@Test
public void shouldRegisterUser() {
    //Given
    String email = System.currentTimeMillis() + "[email protected]";

    //When
    ResponseEntity<UserInfo> entity = registerUser(email);

    //Then
    assertEquals(HttpStatus.OK, entity.getStatusCode());

    UserInfo registeredUser = entity.getBody();
    System.out.println ("The registered user ID is " + registeredUser.getUserId());

    String receivedMessages = receiver.getMessages().toString();
    assertTrue(receivedMessages + " expected to contain " + email,   receivedMessages.indexOf(email) != -1);
}

private ResponseEntity<UserInfo> registerUser(String email) {
    String password = "secret";
    UserInfo userInfo = new UserInfo(email, password);

    RestTemplate restTemplate = new RestTemplate();
    return restTemplate.postForEntity("http://localhost:8080/users/registration", userInfo,  UserInfo.class);
}
}

Answer 1

Update for Spring 2.0.

My Tomcat was starting fine when running the app, but wasn't starting for me in my tests. @Miodigy's answer didn't work for me, but this did:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@RunWith(SpringRunner.class)
class TokenTest {
    @Autowired private SavedSearchesController controller
    @LocalServerPort private int port

Important points are:

@SpringBootTest - make sure to add the webEnvironment parameter.

@LocalServerPort - this is where spring will inject the random port.

Without webEnvironment Tomcat was not starting for me in my tests.

Answer 2

scan ports, set server port to a free one found

@IntegrationTest("server.port:0")

discover the port number

@Value("${local.server.port}")
int port;

add port to url

restTemplate.postForEntity("http://localhost:"+port+"/users/registration"...
