Good books and resources on user interface testing

Question

I am looking for good books and articles on user-interface testing.
What they should contain (one or more of):

• different test methods/strategies
• examples, use cases
• naming pros and cons for different methods
• testing functionality
• testing usability (less important for my me but still good)
• something important I might have forgotten :-)

What they should not be:

• Only about general tests and not gui tests
• describing a test framework limited to a single language

What are the best resources you know of?
(preferably language agnostic)

Edit
Added difference functionality and usability testing.(Thanks to Chris Clark for pointing this out)

Answer 1

n.b. On a more careful reading, I realize you are asking about testing as in unit-testing, not usability testing. So feel free to downvote me, but I'm still posting this because I love the book so much :)

I would highly recommend the book "Rocket Surgery Made Easy" by Steve Krug, one of the luminaries in the field and author of the classic text "Don't Make Me Think", which is a guide to web usability. RSME might not cover everything that you're interested in, but it provides a great methodology for anyone to do simple, fast usability tests. It's a quick and fun read with a lot of asides that provide fodder for further research.

Here is a sample chapter.

Answer 2

Don't Make Me Think is the good resource on User Acceptance Design, Development and Testing.
