Mockito,JUNIT-->How can be stub out the SORT.BY parameter in when() and verify() calls?

Below is the method from controller

@RequestMapping("addWorkout")
public  String addWorkout(ModelMap modelmap,HttpSession session) {
    LOGGER.info("Inside addWorkout,Start");
    int userId=(int)session.getAttribute("userId");
    // modelmap.addAttribute("userId",id);

    List<Workout> workoutList = workoutRepo.findByUserId(userId,Sort.by(new Sort.Order(Direction.DESC, "date"), new Sort.Order(Direction.DESC, "startTime")));
    modelmap.addAttribute("workoutList", workoutList);
    modelmap.addAttribute("exerciseList", exerciseRepo.findAll());
    LOGGER.info("Inside addWorkout,end");
    return "AddWorkout";
}

How do i write when call for below line of code?it could be any simple type of match for SORT parameter workoutRepo.findByUserId(userId,Sort.by(new Sort.Order(Direction.DESC, "date"), new Sort.Order(Direction.DESC, "startTime")));

Below is the test method i have written for the above controller method

@Test
void addWorkoutTest() {
    int userId = 1;

    List<Workout> mockWorkoutList = new ArrayList<>();
    List<Exercise> mockExerciseList = new ArrayList<>();
    when(exerciseRepo.findAll()).thenReturn(mockExerciseList);
    when(session.getAttribute("userId")).thenReturn(userId);
    String result = workoutController.addWorkout(modelMap, session);
    verify(exerciseRepo, times(1)).findAll();
    verify(session, times(1)).getAttribute("userId");
    verify(modelMap, times(1)).addAttribute("workoutList", mockWorkoutList);
    verify(modelMap, times(1)).addAttribute("exerciseList", mockExerciseList);
    assertNotNull(result);
}`

i am unsure how to handle the SORT parameter part.Looking for different ways to handle the SORT parameter in when() call.Any examples will help me learn

when(workoutRepo.findByUserId(anyInt(), ) ).thenReturn(mockWorkoutList);

userId is an int and Sort overrides boolean equals(Object), so you can match directly on the exact arguments:

when(workoutRepo.findByUserId(userId, Sort.by(new Sort.Order(Direction.DESC, "date"), new Sort.Order(Direction.DESC, "startTime"))))
    .thenReturn(List.of(…));

You can also use eq matchers (Matchers.eq):

when(workoutRepo.findByUserId(eq(userId), eq(Sort.by(new Sort.Order(Direction.DESC, "date"), new Sort.Order(Direction.DESC, "startTime")))))
    .thenReturn(List.of(…));

or match with any() if you don't care about the actual value:

when(workoutRepo.findByUserId(eq(userId), any()))
    .thenReturn(List.of(…));
