I have been asked to work with our UI/UX director recently to test our UI stuffs. I am bit nervous as its completely new area. So far, i have been in functional testing and did test for UI alignment issues. I Just wanted to know how to get started with UI/UX testing ? ANy materials, Blog , links would be appreciated.
I have read two great books written by Steve Krug, which I think are a must read for anyone doing usability testing.
Both are easy to read and you should be able to read both in a day (or two).
Maybe also ask the question on http://ux.stackexchange.com/, guess that community might have better getting started pointers.
I think the best single book to read for your situation is The Design of Everyday Things by Donald Norman. He's the other half Norman / Nielsen group linked in Peter's answer and a pioneer of the usability field.
The concepts in this book are valuable because they are an effective lens through which to evaluate your UI and a useful vocabulary to communicate what you observe.
A made up example:
Uses the shared concepts of constraint and feedback to describe friction in the user experience.
Could be a UX issue, or possibly a bug with form validation, or possibly a bug with posting the form, etc.
There isn't a single website mentioned in this book if I recall, but the underlying concepts are applicable to any user experience, which I find pretty amazing.
Testing mobile apps is very hard. You has so many combinations: devices * operating systems * app versions.
I am sure that many additional points exists. But these come up into my mind at first.
