Unit testing Scala

I just recently started learning the Scala language and would like to do it in TDD-way. Could you share your experiences on the unit testing frameworks there are for Scala and the pros/cons of them.

I'm using IntelliJ IDEA for Scala development, so it would be nice to be able to run the tests with IDE-support.

Have you looked at ScalaTest ?

I've not used it, but it comes from Bill Venners and co at Artima, and consequently I suspect it'll do the job. It doesn't appear to have IDE integration, however.

This blog entry is a little old, but suggests that TestNG is the best option for testing Scala. TestNG will certainly have IDE integrations.

EDIT: I've just realised that I wrote this answer in 2009, and the world has moved on (!). I am currently using ScalaTest, the IDE integration works fine, and I can strongly recommend it. In particular the matcher DSL works very nicely
