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)]     at org.springframework.test.context.BootstrapUtils.resolveExplicitTestContextBootstrapper(BootstrapUtils.java:155)     at org.springframework.test.context.BootstrapUtils.resolveTestContextBootstrapper(BootstrapUtils.java:126)     at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:105)     at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTestContextManager(SpringJUnit4ClassRunner.java:152)     at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>(SpringJUnit4ClassRunner.java:143)     at org.springframework.test.context.junit4.SpringRunner.<init>(SpringRunner.java:49)     at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)     at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)     at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)     at java.lang.reflect.Constructor.newInstance(Constructor.java:422)     at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:104)     at org.junit.internal.builders.AnnotatedBuilder.runnerForClass(AnnotatedBuilder.java:86)     at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)     at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:26)     at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:59)     at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:33)     at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createUnfilteredTest(JUnit4TestLoader.java:84)     at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:70)     at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:43)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:444)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382)     at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192) 

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 {     ... }

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
