Unit testing

Each dialog should be tested in isolation for all possible error conditions. This should be done either by the person who developed the dialog, or, preferably, by another member of the project team. The following lists should be drawn up beforehand:

• The conditions to be tested
• The data used to test these conditions
• The expected results

The documented results of the testing should be approved by the project leader. When the unit testing is completed successfully, the dialog should be submitted for subsystem or integration testing. For dialogs that operate independently, no testing should be required beyond unit testing.
