Browserless, ant-task-oriented Javascript Unit Testing?

I'm looking for a javascript unit test framework that I can use as part of my automated maven build. This CANNOT use an actual browser, and it MUST be fully browserless.

I've tried looking at a few posts on SO, but none seem to meet my needs. Is there such a javascript unit tester? I'm anxious to find out.

I was trying to solve the same problem. It seems, that this is not as common, as one might think from our perspective.

RhinoUnit looks very good.

If you need browser capabilities within Rhino, take a look at
