**Validation Test Description**
This unit test verifies the correctness of the output motor torque :ref:`torqueScheduler`.
The inputs provided are the lock flag and the time at which thr control is switched from
one degree of freedom to the other.
**Test Parameters**
Args:
lockFlag (int): flag to determine which torque to use first;
tSwitch (double): time at which torque is to be switched from one d.o.f. to the other;
**Description of Variables Being Tested**
This unit test checks the correctness of the output motor torque msg and the output effector lock msg:
- ``motorTorqueOutMsg``
- ``effectorLockOutMsg``.
The test checks that the output of ``motorTorqueOutMsg`` always matches the torques contained in the input msgs
and that the flags contained in ``effectorLockOutMsg`` are consistent with the schedule logic that the user is requesting.
