Experiment 6: Develop test cases for unit testing and integration testing

Objective: To develop test cases for unit testing and integration testing for the passport automation system.

Outcome: CO3

Test Cases for Unit Testing:

·       Verify that the user can log in to the system using valid credentials.

·       Verify that the user cannot log in to the system using invalid credentials.

·       Verify that the user can update their personal information in the system.

·       Verify that the user can search for passport application status.

·       Verify that the system displays an error message if the user enters invalid data in the passport application form.

Test Cases for Integration Testing:

·       Verify that the user can submit a passport application form and it is saved in the database.

·       Verify that the user can pay the application fees using a valid payment method.

·       Verify that the system generates a unique passport application number for each application.

·       Verify that the user can track the progress of their passport application.

·       Verify that the system sends email notifications to the user when the application is processed and when the passport is ready for collection.
