My last project used jsUnit, but after some searching around, i found a great alternative: jqUnit!

It is a simple wrapper around the jQuery testrunner, so it is possible to run it with any library. And it is jsUnit compatible, so you can reuse all old tests.

Other features:

• simple, just write test(‘it should find ids’,function(){ok(true)})
• very light syntax ok(value,msg), equal(actual,expected,msg)…
• DOM reset after every test
• clean output, that can be opened/closed by clicking test-names
• real user interaction ca be simulated with triggerEvent
