How to mock which is returning list of integers on some where condition?

Question

I blocked in below step

var ids = _repository.GetIQueryable<Customers>().Where(lrt => lrt.IsActive == true &&
                       lrt.NextRoleId == defaultRoleSetting.RoleId &&
                       lrt.NextUserId == null).Select(x => x.MasterId).Distinct().Take(100).ToHashSet();

I tried this but I don't find the right Returns syntax

_mockRepository.Setup(s => s.GetIQueryable<Customers>()).Returns<List<int>>(ids =>
{
  return ????;
});

Answer 1

by below code my issue solved thanks every one.

var fakeCustomers = FakeCustomers();
_repository.Setup(s => s.GetIQueryable<Customers()).Returns(fakeCustomers.AsQueryable());
    
    private List<Customers> FakeCustomers()
            {
                string fakeData = @"[{
      'Id': '118',
      'CreatedBy':'00000000-0000-0000-0000-000000000000',
      'SId':'4',
      'UserId':'00000000-0000-0000-0000-000000000000',
      'NId':'7'
    }]";
                return JsonConvert.DeserializeObject<List<Customers>>(fakeData);
            }
