> Unit Testing - Do you unit test your JavaScript?

IMHO the simple boolean answer doesn't really tell you that much. There is a big difference between someone having only a few unit-tests for a huge codebase, v/s someone having most of the code covered by unit tests.

Additionally JavaScript is used a lot for user interface related stuff, where unit tests can often be more trouble than they're worth; instead full-scale functionality testing (like with Selenium) could be more useful thing to do.

That's always been my gripe with client-side JS tests as well. For large frameworks or libraries (like jQuery), I'd definitely unit test in a heartbeat, but for end-developer code which is mostly code fired after the DOM is ready, calling plugins verbatim, and binding user input to actions, Selenium is really a much better use of my testing time than adding in unit tests for those particular use cases.
