You now need to add a test fixture file to the unit test project.
This opens the Select a wizard dialog box.
This opens the New COBOL Unit Test dialog box.
The MFUPD_aircode.cpy test fixture file is created within the TestAirportDemo unit test project. An additional copybook that serves as the Working Storage section of the test suite is required in order to utilize the mfunit.cpy copybook, which contains some essential declarations for the test runner.
The New COBOL Copybook dialog box is displayed.
The copybook is immediately opened in the editor.
