Test Case For Lift | Lift Test Cases Templates

This question is asked in many interviews regardless of years of experience. I have noticed that the more experience you have, the more basic questions like these appear. So here are some of my test scenarios and negative test cases for Elevator, aka Lift. 

Test Scenarios: You can come up with plenty of test scenarios, but for the easy to remember way, I suggest the following test scenarios.

Capacity

Assum lift takes max. 300KG weight. So by applying the boundary value analysis, we can decide on more test cases.

• How much weight can it take to go up?
• How much weight can it take down w.r.t to specified weight?

Usability

A lift has a number pad and a few controls to operate itself.

• Are the controls self-explanatory?
• Are the controls usable by a blind person?
• Are the controls guided by voice messages?

Functionality

• Is the functionality as per specification?
• Is the control functioning as it is supposed?
• What happens when it is overweight, does it still work?
• What happens if the auto-close functionality is not working?

Comfort

• Is the control pad comfortable to use?
• Is the experience inside lift makes the person uncomfortable due to gravity pull?
• Is the lift making noise while going up or down?

Height, Weight & Volume Scenario Of List

The test cases on height, weight, and volume can be made based on the specifications. Few more test cases that can be added into this are as follows:

• How much time does it take to reach every floor?
• How much time does it take from the top of the building to the ground floor?
• How many people can it take regardless of their weight?
• What happens when it takes more people than the capacity?
• What happens to the people inside the lift when a power failure happens?
• How can many runs lift make on power backup?
• Does it show the right number on the floor?
• Does the lift gets blocked when more than 1 floor makes a request?

Negative Test Cases for Lift

• Add one more person than the specified weight and check the response.
• Add a number of people regardless of weight and check the volume limitations.
• Create smoke or fire inside the 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.

Functional Test Cases For Lift

• Check the first lift is made with which material. (Is it made by steel or iron.)
• Check What type of doors is grill type or door type.
• Check which side of the door buttons switches board is there or not.
• Check-In that switchboard, how many buttons are there?
• Check for the appropriate no of buttons?
• Check when I touch the open button is that lift opening or not
• Check What happens if I touch the open button twice?
• Check What happens when I press the open button while the lift is moving and in the middle of the two floors?
• Check What happens when I press the open button for some time?
• Check for the sound when the lift is opening.
• After entering into the lift press up button. In which direction am I moving?
• After entering into the lift, press down the button. In which direction am I moving?
• When a person is in the lift, any light is there or not?
• How many persons at a time will carry the lift in a sense in moving time.
• Without load, if we press the up button, is it moving or not.
• Without specifying the floor number, if we press the up or down button, what is happening?
• What happens if the lift is in overload mode (overload sound will come before moving, or it moves).
• Without load, if we press the up button and specify the floor number, what is happening?
• After entering into the lift, doors are automatically closing, or we have to close?
• When the lift is on the ground floor, we are going inside the lift and specify the floor number zero(ground floor).then what is happening.
• After getting into the lift, one person is there. He wants to up, but we want to go down already. He specified the floor number before we enter into the lift. Afterwards, we determined our floor number, then what is happening?
• When we are outside, we want to open the door. But inside a person wants to close the door when both are operating the lift, what will happen?
• Enter in the lift, specify the floor, say four, and check for the corresponding floor?
• Check Lift is moving, and the power break off. Does the alarm blow in the control room that there is power break off?
• Check for the case how the inside person informs the lift man that he got stuck in the lift (if there is a phone button, does it works)? Also, check for the response time to start lift again?
• When a person is in the lift, any light is there or not?
• How many persons at a time will carry the lift in the since in moving time.
• Without load, if we press the up button, is it moving or not.
• What happens without specifying the floor number if we press the up or down?
• Without load, if we press the up button and specify the floor number, what is happening?
  Is the door get closed itself or have to close manually.
• If the door closed automatically, check for the closing time?
• If the door closed automatically, also check for the sensor? Suppose the closing time is 2 min, and it passed, and people are still getting in. What happens does the door get closed or wait for the people to get in?
• What happens when you press the same floor number on which lift is already there?
• After getting into the lift, one person is there he wants to go up, but we want to go down already he specified the floor number before we enter into the lift. After that, we determined our floor number, then what will be the priority of the lift?
• Lift is empty and is moving downwards I entered and want to go up. Is there the button to change the direction of the lift and the button working?
• Is the floor number displayed up inside the lift correct?
• When the outside person wants to open the door, the inside person wants to close the door at the same time.

Test Scenarios For List

• Verify the dimensions
• Verify the type of door is as per the specification
• Verify the type of metal used in the lift interior and exterior
• Verify the capacity  in terms of the total weight
• Verify the buttons in the lift to close and open the door and numbers as per the number of floors
• Verify that lifts moves to the particular floor as the button of the floor is clicked
• Verify that lifts stop when up/down buttons at particular floor are pressed
• Verify if there is an emergency button to contact officials in case of any mishap
• Verify the performance of the floor – the time is taken to go to a floor
• Verify that in case of power failure, it doesn’t free-fall and get halted on the particular floor

• Observe when we r come out from lift, door closing operation.

Negative Test Case For List

• press enter button when we are outside.
• Observe door opening operations.
• Wait outside some time when the door is opened.
• When we are inside, observe door closing operations without pressing the closing button.
• Observe door operations when we middle in the door.
• Check lift working when the power is off.
• Observe the lift working when the power will be low voltage.
• Observe the lift working operations when the heavy load is having in the lift.
• Verify door closing operations when the heavy load is in the lift.
• Check if power is suddenly off when the lift is in working

You can, of course, come up with many more test cases based on the available data. I hope the test cases here have helped you during your interviews or for your personal use. Let me know your suggestions in comments
