Got this also from the win_tech_off_topic list:
Here's something that looks really promising: NUnitASP. Since i'm currently not doing ASP.NET development, I can't really test it thoroughly, But if it's half as productive as NUnit(And NUnitAddin 2.0combined) I bet it's gonna help someone(lots of someone's!) with their ASP.NET development. I'll put it in my XP/Unit Testing Links collection for safe keeping.
