- Updated test cases in `test_workers.py` to replace dictionary-based constraints with instances of `PreShiftConstraint`, `PostShiftConstraint`, and `MaxShiftsPerWeekConstraint`. - Added a new test `test_worker_assign_as_block_preference2` to verify worker preferences for block assignments. - Marked tests as slow where appropriate to improve test suite performance.
