How to mock Spring's @Retryable attributes such as maxAttemps and delay in SpringBootTest

Question

I have a method which I'm trying to test

@Retryable(value = {SocketTimeoutException.class},
             backoff = @Backoff(delay = 10000),
             maxAttempts = 4)
public String getNewString(String oldString) throws IOException{
   ...
}

I have created it's test case like so:

@SpringBootTest
@RunWith(SpringRunner.class)
public class TestStrings {
  @Test(expected = SocketTimeoutException.class)
  public void testGetNewString() throws IOException {
     ...
  }

Everything works great, the test case runs 4 times with a delay of 10sec. But I want to change the attributes of @Retryable, namely maxAttempts from 4 to 2 and delay from 10s to 0.5s for this specific test case. I want to do this so that when running the test cases it should not wait for a long time and the test case should end quickly meanwhile also testing the retry functionality.

You cannot, unless you make them configurable and run with a specific test configuration. — M. Deinum, Aug 05 '20 at 12:05
Use the `...expression` variants with property placeholders. — Gary Russell, Aug 05 '20 at 14:47

Use

@Retryable(maxAttemptsExpression = "${max.attempts:4}", 
        backoff = @Backoff(delayExpression = "${delay:10000}"))

and set the properties in your test case.

I almost forgot I could do this. Was working along the lines of mocking RetryProperties with the specific properties. Thanks! – Paras Thakur Aug 06 '20 at 15:33
