Unit testing in flex

Question

Are there any unit testing solutions for Flex? or actionscript 3?

If so, what are their features? Any UI testing abilities? Functional testing? Any pointers, examples, libraries or tools that you can share?

Answer 1

FlexUnit is pretty awesome - http://opensource.adobe.com/wiki/display/flexunit/FlexUnit

Also ASUnit - http://asunit.org

They are both pretty similiar and both haven taken quite a bit from frameworks like JUnit.

FlexMonkey (http://code.google.com/p/flexmonkey/) although I haven't used it myself seems to do UI unit testing.
