I have wrote a short e-mail[1] about running tests on PhantomJS, but that was a few months ago. Run all tests in the most recent version of PhantomJS, fix failures and tag tests that do not run in PhantomJS by design with @phantomjs-bug. (For example of @phantomjs-bug tag see aftv5.feature[2] file.)
