Programmer-written unit tests were once taken for granted, later fell into disfavor, and are now generally considered a best practice. The NUnit framework is the most widely adopted unit-testing tool in the .NET world.

This talk will briefly introduce NUnit for those who are new to it and will go on to cover some of the newest and coolest features:

• What unit-testing is about. How we did it historically. Why it fell into disfavor in some circles and why it's back again. How we do it today: xUnit frameworks.
• Problems test frameworks must solve. How NUnit solves them. Demonstration of NUnit. Attributes, Asserts and Exceptions. Cross-platform use of NUnit. New features. How to get involved.
