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

Question

I tried:

@RunWith(SpringJUnit4ClassRunner.class) @EnableAutoConfiguration(exclude=CrshAutoConfiguration.class) @SpringApplicationConfiguration(classes = Application.class) @WebAppConfiguration public class LikeControllerTest { 

However the CRaSSHD still starts up. While currently it doesn't harm the test, I'd like to disable unnecessary modules during unit testing to speed up and also avoid potential conflicts.

Answer 1

Another simple way to exclude the auto configuration classes,

Add below similar configuration to your application.yml file,

--- spring:   profiles: test   autoconfigure.exclude: org.springframework.boot.autoconfigure.session.SessionAutoConfiguration 

Answer 2

Top answers don't point to an even simpler and more flexible solution.

just place a

@TestPropertySource(properties= {"spring.autoconfigure.exclude=comma.seperated.ClassNames,com.example.FooAutoConfiguration"}) @SpringBootTest public class MySpringTest {...} 

annotation above your test class. This means other tests aren't affected by the current test's special case. If there is a configuration affecting most of your tests, then consider using the spring profile instead as the current top answer suggests.
