Tip for Profiling NUnit Tests
This is just a tiny little note that can save you some precious time. This article explains exactly what you need to do in order to profile NUnit tests with dotTrace (gotta love products with special placement of capital letters) 4.0, except it misses an important detail. The latest versions of NUnit run the actual tests in a separate process, called nunit-agent.exe. So, if you profile nunit-console.exe you won’t see your code there at all. You have to run NUnit in a single process mode. To do that just add /process:Single to the nunit-console command line arguments, and everything should work nicely now.
