There are some good checkpoints covered over at this website. He has 3 or 4 articles on the subject:
Evaluating website accessibility part 2, Basic Checkpoints
Main points he covers in relation to software is using following Firefox extensions:
- Fangs screenreader emulator: http://www.standards-schmandards.com/index.php?2004/11/22/8-fangs-release-05
- Web Developer Toolbar: http://chrispederick.com/work/webdeveloper/
I use the Web Developer Toolbar to turn lots of things off quickly for a page:
- javascript
- images
- background colours
- background images only
- css
- change layout to small screen rendering
- highlight names of div ids and classes
- linearise the tables
- check images without alt tags
- check links without title tags
- display colours used as html equivalent in a square
It also has access to most of the validators and online web accessibility checkers.
I use the colour tools at http://wellstyled.com/tools/colorscheme2/index-en.html as I feel this is the best tool out there. Use it to create colour schemes and check different forms of colour blindness against what you have set up.
