How to exclude *AutoConfiguration classes in Spring Boot JUnit tests?

Question

I tried:

@RunWith(SpringJUnit4ClassRunner.class)
@EnableAutoConfiguration(exclude=CrshAutoConfiguration.class)
@SpringApplicationConfiguration(classes = Appl         


        

Answer 1

If the issue is that your SpringBootApplication/Configuration you are bringing in is component scanning the package your test configurations are in, you can actually remove the @Configuration annotation from the test configurations and you can still use them in the @SpringBootTest annotations. For example, if you have a class Application that is your main configuration and a class TestConfiguration that is a configuration for certain, but not all tests, you can set up your classes as follows:

@Import(Application.class) //or the specific configurations you want
//(Optional) Other Annotations that will not trigger an autowire
public class TestConfiguration {
    //your custom test configuration
}

And then you can configure your tests in one of two ways:

1. With the regular configuration:

   @SpringBootTest(classes = {Application.class}) //won't component scan your configuration because it doesn't have an autowire-able annotation
   //Other annotations here
   public class TestThatUsesNormalApplication {
       //my test code
   }
   

2. With the test custom test configuration:

   @SpringBootTest(classes = {TestConfiguration.class}) //this still works!
   //Other annotations here
   public class TestThatUsesCustomTestConfiguration {
       //my test code
   }
