In my previous post, I discussed the basics of using Gallio, MbUnit, and WatiN to test web applications. In the previous example you could continue to add tests to the class by creating additional test methods and marking them with the test attribute. However, you could not guarantee what kind of order those tests would run in. Fortunately, MbUnit/Gallio is a flexible enough framework to allow you to create orderd test suites which is a common need for functional testing.
