Unit Testing
When the program is started, user is prompted to enter the user name. Here, the security option is found to be working well. When wrong password is log in the user is not able to advance to any other part of the program. Upon keying in the right combination for user name and password, the user is allowed to advance to the other part of the program.
Upon logging in, the menu window is shown, here the user can choose to access any part of our program. The client option will lead the user to the client window. Here, the addition, deletion and edition of a client is tested. The database is updated every time each function is called. When the exit button is pressed the menu button will once again appear.
In the goods option , the addition, deletion and edition will be checked just like in the client option.
In the scheduling option, besides testing the updating of the database just like those done for the previous two options, a test is done to ensure that the transaction is done at each time allocated.
The program is found satisfactory in fulfilling the requirement of the client. All the needed functions are implemented.
