JUnit-testing a Spring @Async void service method

I have done by injecting ThreadPoolTaskExecutor

and then

executor.getThreadPoolExecutor().awaitTermination(1, TimeUnit.SECONDS);

before verifying results, it as below:

  @Autowired
  private ThreadPoolTaskExecutor executor;

    @Test
    public void testAsyncMethod() {

        Foo testData = prepareTestData();

        someService.asyncMethod(testData);

        executor.getThreadPoolExecutor().awaitTermination(1, TimeUnit.SECONDS);

        verifyResults();
    }

For @Async semantics to be adhered, some active @Configuration class will have the @EnableAsync annotation, e.g.

@Configuration
@EnableAsync
@EnableScheduling
public class AsyncConfiguration implements AsyncConfigurer {

  //

}

To resolve my issue, I introduced a new Spring profile non-async.

If the non-async profile is not active, the AsyncConfiguration is used:

@Configuration
@EnableAsync
@EnableScheduling
@Profile("!non-async")
public class AsyncConfiguration implements AsyncConfigurer {

  // this configuration will be active as long as profile "non-async" is not (!) active

}

If the non-async profile is active, the NonAsyncConfiguration is used:

@Configuration
// notice the missing @EnableAsync annotation
@EnableScheduling
@Profile("non-async")
public class NonAsyncConfiguration {

  // this configuration will be active as long as profile "non-async" is active

}

Now in the problematic JUnit test class, I explicitly activate the "non-async" profile in order to mutually exclude the async behavior:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@IntegrationTest
@Transactional
@ActiveProfiles(profiles = "non-async")
public class SomeServiceIntTest {

    @Inject
    private SomeService someService;

        @Test
        public void testAsyncMethod() {

            Foo testData = prepareTestData();

            someService.asyncMethod(testData);

            verifyResults();
        }

        // verifyResult() with assertions, etc.
}
