How to load a @Profile service in spring-test?

Question

How can I load a @Profile component in a spring-test, without having to explicit launch that profile as startup profile?

@Configuration
@Profile("dev1")
public class MvcInterceptor extends WebMvcConfigurerAdapter {
    //adding a custom interceptor
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new MappedInterceptor("/customer", new CustomerInterceptor()));
        super.addInterceptors(registry);
    }

}


@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
//@ActiveProfiles("dev1") //I don't want spring to load the full profile chain
public class SpringTest {
    @Autowired
    protected MockMvc mvc;

    @Test
    public void test() {
        mvc.perform(get(...))...;
    }
}

Question: how can I load the MvcInterceptor without using @ActiveProfiles("dev1") on the testclass?

Because, dev1 profile would imply many more resources being set up, which I won't need for that test. I just want to load the MvcInterceptor, but without having to launch the full profile.

Impossible?

It works by initializing the a Bean in a static inner @TestConfiguration class.

public class SpringTest {
    @TestConfiguration
    public static class TestConfig {
        @Bean
        public MvcInterceptor interceptor() {
            return new MvcInterceptor();
        }
    }
}

Though MvcInterceptor is @Profile depending, it will be wired for the test.
