I have two services MyRepo and RepoWrapper, RepoWrapper is composed of MyRepo which has some method annotated with some spring cache annotations.

I want to configure a test context with only the necessary classes and cache enabled, and most importantly without using @SpringBootTest which loads the entire application context.

here are my classes:

@Repository
interface MyRepo: CrudRepository<SomeEntity, Long>

@Repository
@Primary
class RepoWrapper(val myRepo: MyRepo): CrudRepository<SomeEntity, Long> by myRepo {

  @Cacheable
  fun foo(arg: Any) {
    // ..
  }
}

Here is my attempts to load smaller application context.

@ExtendsWith(SpringExtension::class)
@ContextConfiguration(classes = [TestConfig::class, RepoWrapper::class])
class MyIntegrationTest {

  @MockBean
  lateinit var myRepo: MyRepo

  @Autowired
  lateinit var cacheManager: CacheManager

  @Autowired
  lateinit repoWrapper: RepoWrapper

  @Test
  fun mytest() {
    assertTrue(true)
  }}
}

@TestConfiguration
class TestConfig {
  @Bean
  fun cacheManager() = ConcurrentMapCacheManager("mycache")

  @Bean
  fun repoWrapper(myRepo: MyRepo): RepoWrapper = RepoWrapper(cacheManager(), myRepo)
}

How come when I remove the RepoWrapper from the ContextConfiguration classes, or remove it’s bean from TestConfig, Spring seems not able to load the test context ?
