Test Cases


Part 1
Test Inputs
1. inp_gr_sensor_up
A.  Check if the sensor works by tapping it and seeing if the motor stops.

2. inp_gr_sensor_down
A.  Check if the sensor works by tapping it and seeing if the motor stops.

3. inp_gr_tog_switch
A.  Check if the toggle switch works by moving the switch and seeing if the motor moves.

Part 2
checking constants.
1. ON
A.  I will flip the switch, I expect the motor to go clockwise

2. OFF
A.  I will flip the switch, I expect the motor to go counter clockwise

3. C_GR_SWITCH_UP
A.  I need to check if the switches are corresponding with the ON and OFF constants.

4. C_GR_SWITCH_DOWN
A.  I need to check if the switches are corresponding with the ON and OFF constants.

5. C_GR_REV
A.  I will see if the speed on the motors are fast with not burning out the motor.

6. C_GR_FWD
A.  I will see if the speed on the motors are fast with not burning out the motor.

Part 3
debug all valuse to assure correctness

Case 1
INPUT

Flip the grab switch up.  (INPUT = 1)

OUTPUT

The grabber should turn into the locking position.  (OUTPUT = 225)

Case 2
INPUT

Flip the grab switch from up to down.  (INPUT =1 then 0)

OUTPUT

The grabber should turn back into the open position.  (OUTPUT = 225)

Case 3
INPUT

The switch is in the default position of down.  (INPUT = 0)

OUTPUT

The grabber should stay in the open position.  (OUTPUT = 127)

Case 4
INPUT

The switch is was in the up position and is still in the up position. (INPUT = 1)

OUTPUT

The grab should stay in the closed position.  (OUTPUT = 127)
