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

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.

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 {
    ...
}

Just Remove the @SpringBootTest and everything work fine. I had the same problem with using @SpringBootTest and @DataJpaTest, this error raised when I upgraded the pom.xml parent springboot version to 2.1.0 as below. When I was using version 2.0.5, this error was not raising.

@RunWith(SpringRunner.class)
//@SpringBootTest//(classes = KalahApplication.class)
// DataJpaTest supports rollback after running every test case
@DataJpaTest
public class GameRepositoryTest {

pom.xml

   <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
   </parent>

I know its too late to answer this question, but it may help someone in the future so... I had the same issue and after some research, i found that there shouldn't be @WebMvcTest if there is @SpringBootTest. so just remove @WebMvcTest and @SpringBootTest is taking care of the rest.

It happens because you declared both @WebMvcTest and @SpringBootTest, I resolve my same problem by removing @SpringBootTest
