There are quite a few nice features in the new 2.5 release of NUnit so if you’ve not yet checked it out please do so. I’ve migrated to it in all our solutions at work and we’ve had no problems, we did have to upgrade to the latest versions for TestDriven.Net and TeamCity, but hey, upgrading is a good thing.
One thing I really like is the ValuesAttribute, if you’ve done parameterized tests (that were previously available in the NUnit.Framework.Extensions library) this is something similar. Just tag your test as a normal Test-method but add a parameter and tag that parameter with the ValuesAttribute like this:
This will result in three tests being run, one for each value, quite nice.
The really cool thing is that you can add more than one parameter each tagged with this attribute and the number of tests will be the cross-product of the values.
