I went looking to find the order in which NUnit executes the test attributes/events.  Oddly enough, I couldn't find it.  (Maybe I'm not googling it properly.)

Anyway, here's the NUnit attribute event order:

1. TestFixtureSetUp
2. SetUp
3. Test
4. TearDown
5. Repeat steps 2, 3, and 4 for each test that's being run in this fixture.
6. TestFixtureTearDown
