Spring boot 1.4 Testing : Configuration error: found multiple declarations of @BootstrapWith
JavaSpringSpring MvcSpring BootSpring TestJava Problem Overview
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.
Java Solutions
Solution 1 - Java
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 {
...
}
Solution 2 - Java
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.
Solution 4 - Java
It happens because you declared both @WebMvcTest and @SpringBootTest, I resolve my same problem by removing @SpringBootTest
Solution 5 - Java
Hope this will help. It worked for me after taking it off @SpringBootTest, and was testing the web later for the same @AutoWired would throw an error as i'd used interface. Rather mock the same it worked.

Looks like you want to write integration test. That's why i recommend use only
@SpringBootTest(classes = Application.class)
If you want to use junit4, then add
@RunWith(SpringRunner.class)
Solution 7 - Java
in Junit 5 could be:
@ExtendWith(SpringExtension.class)
@DataJpaTest
class DeliveryRepositoryTest {
@Autowired
private DeliveryRepository repository;
...
}
Solution 8 - Java
I had a similar issue with this set up:
@WebMvcTest
@SpringBootTest
@ContextConfiguration(classes = {Controller.class})
public class ControllerTest {
@Autowired
private MockMvc mockMvc;
...}
and I have a Spring service bean autowired in the controller.
The final correct set up is to just leave @WebMvcTest
, which provide the MockMvc, and add a @MockBean
for the service.
My final, working, test is:
@WebMvcTest(Controller.class)
public class ControllerTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private CustomerService customerService;
...}
Solution 9 - Java
You must use only @DataJpaTest
.
Remove @SpringBootTest
in your Testclass
