Testing Scenarios

Test a Vending machine?
· I’ll try to test it with different coins of the same currency and I’ll see if it gives change back.
· I’ll try to test with different currencies.
· I’ll try to put a fake input coin and see how it reacts to it
· I’ll try to press the menu button before inserting coins.
· I’ll try to press two menu buttons simultaneously.
· I’ll try to press and hold the menu button after I put a coin
· I’ll try to open the door
· I’ll put two coins one after the other before pressing any button and I’ll try to get two items. I’ll try to test if it can manage tasks and etc.
· I’ll test it by putting coins and pressing item button at the same time and I’ll see how it reacts
· I’ll put an item which has a size greater than the hole size of the vending machine and I’ll try to buy that product and If it doesn’t work I’ll try to buy another product, here I’ll try to see if the bigger one blocked the way.
· I’ll flip it up side down and see if it can give me certain item.
· I’ll disconnect the power cord after I put coins and connect it again and press the button and see if it can handle the request which was in the process before the power failure.
· I’ll try to test it if it can operate with different power supplies like main supply and generator etc.
· I’ll try to test its compatibility with the environment.

How would you design the lights at a traffic intersection?

See how creative they are. In particular, synchronizing with lights at other intersections, how they provide smooth flow of traffic (turns etc). Do they consider traffic patterns (rush hour/ special event/ emergency vehicles)?
Solution

There are so many processes to consider these are as follows
· Serving traffic moving straight from east to west
· Serving traffic coming from east and turning to the right at the intersection
· Serving traffic coming from east and turning to the left at the intersection
· Serving traffic moving straight from west to east
· Serving traffic moving from west and turning to the right at the intersection
· Serving traffic coming from west and turning to the left at the intersection
· Serving traffic moving straight from north to south
· Serving traffic coming from north and turning to the right at the intersection
· Serving traffic coming from north and turning to the left at the intersection
· Serving traffic moving straight from south to north
· Serving traffic coming from south and turning to the right at the intersection
· Serving traffic coming from south and turning to the left at the intersection

TEST CASES FOR TESTING A TOSTER?
Does it handle all common types of breads.
Does it perform toasting well.
I’ll try to examine the performance by repeatedly using a tester and I’ll try to see if the performance degrades through repeated use.
I’ll try to test it with different kinds of bread, pizza slice, cracker type bread, flat bread, bread with high sugar content, very thin,medium,and thick
I’ll turn the taster on for a long time without putting any bread in it and see what happened. Here I’ll try to check if it has a certain controlling mechanism if the temperature is above a certain limit.
I’ll test it with for chemical reaction when it is in contact with a certain chemical.
I’ll test it with different power supplies.
I’ll test its reaction with the environment(like does it generate a certain gas which is harmful to the environment)
I’ll try to adjusting all the controls while operating and see every control produces the required result.
I’ll try to see if there is an electric shock when we touch the body of the toaster.
I’ll put more bread than it can accommodate and I’ll see what happens
I’ll try to flip it on side position and see whether it works well or not.
I’ll put a Frosted bread and see what is going to happen.
I’ll turn the toaster on until it gets very hot and then turn it off and put some bread to toast and see how it handles it.
I’ll try to discover which parts of the toaster to touch when in operation.
Should work with diffent voltage ranges(considering internationalization)


Given a screen with customer name, address, phone number, date of birth, SSN, and functions like ADD, DELETE, UPDATE, what types of tests would you execute (backend and GUI)?

GUI Testing:
· I’ll insert a proper data on each field and press add button.
· I’ll select a certain record and delete it.
· I’ll select a certain record and edit some fields with valid data and press update button.
· I’ll press the add button with out entering data in all fields.
· I’ll press the delete button with out selecting a particular record and see what happened.
· I’ll press the try to update without selecting a particular field.
· I’ll try to add an already existing record and see what happened.
· I’ll try to add a certain data in which certain fields are left.
· I’ll try to add data with long strings for each field.
· I’ll try to add data which is in different language and see what happened.
· I’ll try to add data which has a space or some special characters.
· I’ll try to add data which is inconsistent like negative ssn,birth date which is in the feauture, phone and address which is not valid,
· I’ll try to delete a certain record which doesn’t exist.
· I’ll try to update with out changing any value.
· I’ll try to update a record which doesn’t exist
· I’ll try to update a certain record with empty fields all.

DATABASE TESTING:
· I’ll check to see if a certain record has added to the database after I pressed add button.
· Check to see the performance by adding a record repeatedly in a fast manner.
· I’ll try to add so many records and I’ll see if disk space is a constraint
· I’ll try to delete a record which doesn’t exist and see how the Database reacts to this
· I’ll try to update a certain record with out making any changes.
· I’ll try to update a certain record with an invalid data.
· I’ll try to delete a record from an empty table int that particular database.
· I’ll try to see network failure while performing database operations.
· I’ll try to check how the database handles when I try to put duplicate records.
· I’ll try to execute the above GUI from so many client locations and see if there is a possibility of memory leakage.
Testing Enter File Name Text box of a dialog box
· I’ll try to save the specified file with out specifying a name
· I will try to put a certain specific length character and save it using a save button
· I’ll try to enter a file name consists of only numbers.
· I’ll try to enter a file name which will start with dot.

· I’ll enter a file name which exists but holds a different data format.

Test a clutch pencil
· I’ll try to sharpen a regular pencil
· I’ll try to sharpen diffent pencil which are made up of different materials for example hard, soft wood…etc
· I will try to put a pencil inside a hole with out pressing the clutch
· I will try to sharpen another material which has the same shape as a regular pencil

· I’ll try to see the material composition is it hazardous if it is put in some chemical, is it going to burn.
· I’ll try to see the strength of the material by placing a high load.
· Does it need some safety precaution for children to use it.
· Is it continue to work if one of its components is failed like the arm,clutch or blade…etc
· Does the blade and other metal parts rest if it is stored in a frosted environment.

Test An Elivator?
· I’ll try to load an elevator with some rated load specified by the manufacturers
