Lesson 11 - Unit tests of Commercial Applications III

In the previous lesson, Unit tests of Commercial Applications II, we tested random value generators, database wrappers, and learned how to assert multiple exceptions. We'll finish the overview of the commercial unit test samples with today's lesson. We're going to show how to simulate a form submission, including file attachments, and how to compare generated images against the original image patterns.

Testing forms

If you use a custom library to handle forms, you can't avoid testing it. Forms are the backbone of web applications' functionality, and it should be guaranteed by tests that they are handled well. As an illustration, a simple test of the CheckBox form control follows. The control is represented by a class of the same name. CheckBox instances can be added to a Form class instance, which then renders and processes the entire form.
