You should probably look at some standard resources. http://www.google.com/search?client=opera&rls=en&q=test+accessibility&sourceid=opera&ie=utf-8&oe=utf-8 gave me a page of links to testing tools, plus an article on why standard automated testing is not enough. Anyone who has argued that a DTD cannot support sufficient constraints to express the semantics of HTML (or followed such a discussion) should be ableto understand something of the arguments that would be adduced in such an article.

There is a LOT of stuff on how to test - from the W3C site there is a list of tools of various types, ...

If you want a recommendation, for learning how to do testing Hera [1] is a good tool - it does automated tests as much as it can, guides the user throug the various tests that cannot be completely automated, supports collaborative evaluation, is open source and multilingual (if you want to point out something badly translated I would be happy to work on it), and for entreprise level testing AccMonitor [2] which is efficient, cand can be customised to do all sorts of tests. There is a version of the engine running the free web-based service CynthiaSays [3]. I have been involved in the development of both these tools, and it is some time since I made an effort to really compare tools, so my advice is not impartial and perhaps not up to date, but there are plenty of people working in the field who will discuss their preferences (and the whys and wherefores).
