How can be stub out the SORT.BY parameter in when() and verify() calls?

[udemy course]

How do i stub out the below line of code.

List<Workout> workoutList = workoutRepo.findByUserId(userId,Sort.by(new Sort.Order(Direction.DESC, "date"), new Sort.Order(Direction.DESC, "startTime")));

i am unsure how to handle the SORT parameter.

when(workoutRepo.findByUserId(1,     ) ).thenReturn(new ArrayList<>());
