### Question:
ContinuationTransactionMap { public void delete(User user, Device device) { continuations.remove(new Key(user, device)); } @Inject @VisibleForTesting  ContinuationTransactionMap(); T getContinuationForDevice(User user, Device device); boolean putContinuationForDevice(User user, Device device, T continuation); void delete(User user, Device device);  }### Answer:
@Test(expected=ElementNotFoundException.class) public void testDelete() throws ElementNotFoundException { TestingContinuation expectedContinuation = new TestingContinuation(); testee.putContinuationForDevice(user, device, expectedContinuation); testee.delete(user, device); testee.getContinuationForDevice(user, device); }
