Although accessibility checklists are important, testing for web accessibility requires more than that. Some testing requires tasks which can only be done by a human including testing with a screen reader. It’s best for a regular screen reader user to do the testing, but it’s also good for a developer or designer to do at least the basics (there was a big discussion on this last fall in Should Sighted Developers Use Screenreaders To Test Accessibility?).
Here are some good articles to help learn how to use a screen reader to test for web accessibility:
