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.
