Test Cases for Elevator(Lift)

In most of the cases interviewer ask to write test cases. Today I am helping myself in writing test cases for elevator (lift).But before start writing test case I would like to cast our attention on one of the best thing that is ensured by Software Testing and This is nothing but the Software Quality.

So here I am taking the reference of one of the article “What does product quality really mean” written by Dr. David A Gravin, Ph.D professor of Business Administration Harvard Business School.

Through this article Dr Gravin has defined 5 approaches of defining the Quality of a product from 4 disciplines i.e. Philosophy, economics, Marketing and Operational management and these are as follows taken from onquality.blogspot.com

So I am using the same 4 disciplines that helps in defining the quality of a product for writing my test cases for elevator.

I am going to divide my test cases in these 4 disciplines

1-      Philosophy
2-      Economy
3-       Marketing
4-      Operation Management

Test case for elevator

Philosophy

1-      Verify the height and width and volume of life as per the requirement.
2-      Verify that button for closing lift, opening lift, fan, emergency and all floor numbers should be there on button panel
3-      Verify the presence of display where floor number appears
4-      Verify floor number is being announced on each floor
5-      Verify the light and aroma along with some instrumental music
6-      Verify that maximum number of people  and weight is written on wall and also verify all emergency instructions.
7-      Verify  up and down button  outside the life
8-      Verify the presence of sensor

Economy
1-      Verify power used in operation since this is not the main concern here so I am just leaving this part.

Operation
1-      Verify that lift is able to move up and down
2-      Verify that lift is capable to stop on floors which are pressed in button panel
3-      Verify that lift close when close button is placed or should close once after few time as per manual time
4-      Verify that fan is working on pressing respective button
5-      Verify the sensor
When lift is going to close and if someone has just put any object or body parts in between the lift’s doors
6-      Verify the maximum weighing capacity of life by putting weight
7-      Verify that when weight exceed from standard than it should give some alert message or some alert sound should ring
8-      Verify that light and fan is running at power failure
9-      Verify the jerk on power failure
10-   Verify the speed of lift  , it shouldn’t be fast
11-   Verify that lift stops at right floor i.e. if user click on 2^nd floor then lift should stop on 2^nd floor not on 4^th floor.
12-   Verify the landing speed of lift
13-   Verify the time between two successive floors.
14-   Verify that lift doors can’t be open when lift is moving down or upward
15-   Verify that lift doors are closed when no one is using it
16-   Verify that once lift has crossed certain floor and some person has click to open lift then lift should open when lift comes down at that floor.
17-    Some test cases that is basically based on Reliability

1. Verify working of lift on power failure
2. Verify working of lift once power comes
3. Verify the working of lift once weight exceeds the standard weight. 

Marketing
1-      Since this is mainly done if we are testing lift for sell purpose.
Friends I have tried and now it’s your turn to add value to these test cases.
