I have a spring boot app.

project deps (plugins section):

• id 'org.springframework.boot' version '2.6.1'
• id 'io.spring.dependency-management' version '1.0.11.RELEASE'

And I want to test on of my services that works differently based on some properties.

I have separated set of properties and its values in different profiles, e.g. profile-1 and profile-2. Corresponding application-profile-1.yml and application-profile-2 and placed under src/test/resources.

Let’s say I am trying to test the service behaviour based on:

reporting:
  view:
    mode: <value>

where <value> can be short, full or custom

This is my config that fails:

@SpringBootTest
public OuterTestClass {

    @SpyBean
    SomeDependency someDependency;

    @Autowired
    TypeUnderTest subject;

    @Nested
    @ActiveProfiles("profile-1")
    public class Profile1Tests {

        @Test 
        public void test1() {
            subject.method();
            // verifications
        }

    }

    @Nested
    @ActiveProfiles("profile-2")
    public class Profile2Tests {

        @Test 
        public void test2() {
            subject.method();
            // verifications
        }

    }

}

Execution throws common java.lang.IllegalStateException: Failed to load ApplicationContext ... exception because my beans could not be instantiated with null properties.

It seems to me that the root cause is that @ActiveProfiles is not supported on @Nested classes but outer only. It this a right assumption?

Actually what my goal is to avoid spamming enormous amount of standalone test classes with respective @ActiveProfiles applied on them for readability reasons.

I’ve also tried to apply @TestPropertySource on the nested classes and it doesn’t work as well.

Seeking for advises on my case.
