TestCases for Elevator

FUNCTIONALITY TESTS

Test Cases for Outside Elevator:

=======================
1) You should be able to call elevator from every floor.
2) Elevator alerts arrival with an audible sound.
3) When elevator arrives it should be clear in which direction the elevator is going
4) The direction indicators extinguish when its last occupants are delivered to a floor.
5) The elevator doors open within a reasonable amount of time after arrival
6) The elevator doors remain open within a reasonable amount of time
7) Elevator doors reopen when blocked during closure

Test Cases for Inside Elevator:

======================
1) Pressing all buttons from bottom floor causes elevator to stop at each ascending floor in succession.
2) Pressing all buttons from top floor causes elevator to stop at each descending floor in succession.
3) Pressing only top floor button from bottom floor causes elevator to deliver you to the top floor without stopping.
4) Pressing only bottom floor button from top floor causes elevator to deliver you to the bottom floor without stopping.
5) Elevator stops at next floor in succession no matter when it was pressed.
5) Elevator travels in the same direction until all illuminated buttons have extinguished in that direction.
6) Elevator changes direction when there are no more illuminated buttons in that direction.
7) Elevator remains at the last delivered floor until called upon.
8) Pressed buttons are clearly illuminated until floors are reached.
9) When destination floors are reached their illuminated buttons turn off.
10) Floor numbers are accurate and clearly visible upon reaching their corresponding floors.

PERFORMANCE TEST CASES:

1) The amount of time (speed) elevator travels between floors meets specification.
2) The amount of time elevator waits between opening and closing doors meets specification.

3) Test elevator capacity requirement. Say elevator capacity is 2000KG. Test conditions - 1999, 2000 & 2001.

SECURITY TEST CASES:

1) STOP button causes elevator to stop.
2) Pressing ALARM button reaches security within specified amount of time.
3) Verify elevator's maximum weight capacity meets or exceeds specification.
4) Verify integrity of pulley system
5) Verify integrity of the braking system
 

NEGATIVE TEST CASES:

• Add one more person than the specified weight and check the response of lift.
• Add more number of people regardless of weight and check the volume limitations of lift.
• Create smoke or fire inside lift and check the response.
• Try pressing the open button while the lift is moving.
• Press the stop button before reaching the specific floor.
• Put small obstacles near the sensors that detect auto-close functionality.
