Answer 1

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();
    }
