System: ATM Subsystem: PIN
Designed by: ABC Design Date: 28/11/2004
Executed by: Execution Date:
Short Description: Test the ATM Change PIN service
Pre-conditions
The user has a valid ATM card - The user has accessed the ATM by placing his ATM card in the machine
The current PIN is 1234
The system displays the main menu
Step Action Expected System Response Pass/ Comment
Fail
1 Click the 'Change PIN' button The system displays a message asking the user to enter the new PIN
2 Enter '5555' The system displays a message asking the user to confirm (re-enter)
the new PIN
3 Re-enter '5555' The system displays a message of successful operation
The system asks the user if he wants to perform other operations
4 Click 'YES' button The system displays the main menu
5 Check post-condition 1
Post-conditions
1. The new PIN '5555' is saved in the database
