Spring boot 1.4 Testing : Configuration error: found multiple declarations of @BootstrapWith

Question

By following the official doc here: http://docs.spring.io/spring-boot/docs/1.4.0.M2/reference/htmlsingle/#Testing

i wanted to test one of my REST API method like this:

@RunWith(SpringRunner.class)
@WebMvcTest(LoginController.class)
@SpringBootTest(classes = Application.class)
public class AuthorizationServiceTest {
    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void test() {
        Object returnedObject=his.restTemplate.getForObject("/login", Object.class);
    }
}

As stated in the doc :

The search algorithm works up from the package that contains the test until it finds a @SpringBootApplication or @SpringBootConfiguration annotated class. As long as you’ve structure your code in a sensible way your main configuration is usually found.

I have structured my code properly(atleast i think ):

AuthorizationService : is under package com.xxx.yyy.zzz.authorization;

AuthorizationServiceTest : is under package com.xxx.yyy.zzz.authorizationTest;

I am getting this exception(Full Trace):

java.lang.IllegalStateException: Configuration error: found multiple declarations of @BootstrapWith for test class [com.orangeraid.rasberry.gateway.authorizationTest.AuthorizationServiceTest]: [@org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTestContextBootstrapper), @org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.context.SpringBootTestContextBootstrapper)]

Please help me with this, i have already spent more than 2-3 hours without any luck.

Thanks.

Answer 1

This exception occurs when spring test can not find main configuration class. Try to add @ContextConfiguration anootation to your test class. Follow the spring test documention for more details (section Detecting test configuration)

My example Test class is like this:

@RunWith(SpringRunner.class)
@ContextConfiguration(classes=Application.class)
@WebMvcTest(MyController.class)
public class MyConrollerTests {
    ...
}
