Excluding Application Event Listener in testing?












1















I am facing problem in figuring this out.



I am using caching in my application and loading it on application startup using Listeners.



@EventListener(ApplicationReadyEvent.class)
public void LoadCache() {
refreshCache();
}

public void refreshCache() {
clearCache(); // clears cache if present
populateCache();
}
public void populateCache() {
// dao call to get values to be populated in cache
List<Game> games = gamesDao.findAllGames();
// some method to populate these games in cache.
}


This works all fine when I am running the application. The problem however occurs when I run the test cases, the LoadCache() is being called when the setup is being run. I don't want this to run while the tests are being executed.



This is a sample test case



@RunWith(SpringRunner.class)
@SpringBootTest(classes = GameServiceApplication.class)
public class GameEngineTest {
@Test
public void testSomeMethod() {
// some logic
}
}

If you can move your EventListener in a separate class and make it as Bean, then you can use mockBean in your tests to mock a real implementation.



@Component
public class Listener {

@Autowired
private CacheService cacheService;

@EventListener(ApplicationReadyEvent.class)
public void LoadCache() {
cacheService.refreshCache();
}
}

@Service
public class CacheService {

...

public void refreshCache() {
..
}

public void populateCache() {
..
}
}


@RunWith(SpringRunner.class)
@SpringBootTest
public class CacheServiceTest {

@MockBean
private Listener listener;

@Test
public void test() {
// now the listener mocked and an event not received.
}
}


or you can use profiles to run this listener only in production mode.
