I am trying to write integration test case for one of my rest application which uses mongodb internally to persist the data
@DataMongoTest
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class MainControllerTest {
@LocalServerPort
private int port = 8080;
/* some test cases*/
}
but I am getting below error
java.lang.IllegalStateException: Configuration error: found multiple declarations of @BootstrapWith for test class [com.sample.core.controller.MainControllerTest]: [@org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.autoconfigure.data.mongo.DataMongoTestContextBootstrapper), @org.springframework.test.context.BootstrapWith(value=class org.springframework.boot.test.context.SpringBootTestContextBootstrapper)]
looks like these two are mutually exclusive, so how to do the integration testing .

The @SpringBootTest annotation loads the complete Spring application context. In contrast, a test slice annotation only loads beans required to test a particular layer. And because of this, we can avoid unnecessary mocking and side effects.
Write an End-To-End Test With a Running Server To provide a real web environment, we can tell Spring Boot to do that: @SpringBootTest(webEnvironment = SpringBootTest. WebEnvironment. RANDOM_PORT) @ActiveProfiles("test") class ServerIntegrationTests { @Autowired private WebTestClient webClient; // ... }
Spring Boot provides a @SpringBootTest annotation, which can be used as an alternative to the standard spring-test @ContextConfiguration annotation when you need Spring Boot features. The annotation works by creating the ApplicationContext used in your tests through SpringApplication .
To create integration test in Spring make sure that you have Spring Test in your dependencies and, for example, JUnit. Then you need to put annotation @RunWith(SpringRunner. class) on the test class. And also add Context Configuration to your test with a list of configs in annotation @ContextConfiguration.
Use @AutoConfigureDataMongo with @SpringBootTest and this will resolve this ambiguity issue. @SpringBootTest and @DataMongoTest cannot be used together.
