Integration test not working with @Async and @Retryable

I am working on writing an integration test using JUNIT. Due to @Retryable been used in one of the methods called in the test, I am getting org.springframework.retry.backoff.BackOffInterruptedException when running the test. How to write an Integration Test when the methods involved are @Async or @Retryable ?

Here is the code for the test class and service class respectively-

public class TestEndpointIT {

    @Autowired
    EndpointService endpoint

    @Test
    void testMethod() throws DatatypeConfigurationException, ParseException {
        
        
        ResponseMessage response = endpoint.testService(sm);
        
        assertTrue(response.getResponse().getAckNakResponse() == ResponseType.ACK);
        
    };
    
    
class EndpointService {
    @Async
    @Retryable(value = RuntimeException.class, maxAttempts = 3, backoff = @Backoff(delay = 30000))
    @Override
    public void testMethod() {
    // Code
    }
}...


Following is the stack trace for the same-
