I noticed experimentally that any integration test class annotated with @DataMongoTest does not kill the embedded MongoDB instance it uses. To kill the embedded instance, I have to annotate the test with the annotation @DirtiesContext(classMode = ClassMode.AFTER_CLASS).

@RunWith(SpringRunner.class)
@DataMongoTest
@ContextConfiguration(classes = {MyRepositoryIT.class})
@EnableAutoConfiguration
@DirtiesContext(classMode = ClassMode.AFTER_CLASS)
public class MyRepositoryIT{
   // The tests
}

The problem highlights when you run long pipelines of tests using Maven. The embedded Mongo instances are killed only when the whole testing process terminates.

Is it correct? Am I making something wrong?

I am using Spring Boot 2.2.10, flapdoodle library, JUnit 4, and version 4.0.2 of MongoDB. I am building the system under Windows.
