In order to run these tests, you will need the latest CVS version of SimpleTest (and either place that directory in this directory and call it "simpletest", or make a symlink named "simpletest" pointing to that directory). Note that I run with local modifications to SimpleTest, so things may not work out 100% perfect for you. This might be fixed in the future. :) Additionally, WordPress has some bugs (gasp!). The default theme needs to be hacked a bit so that the pages generate valid XHTML. Specifically, for all versions 2.0+ (at least), search the theme for all instances of "Permanent Link". Replace the immediately following occurrence of with . In WordPress 2.0, you will need to make one further hack -- in wp-admin/admin-functions.php, search for "tinyMCE.configs.length". Add tag for that block, and ]]> immediately before the ending of that block. These modifications should allow the pages to validate, or at least get close enough to well-formedness to allow the automated testing to work.
