Quality Assurance testing for Moodle 2.5 is already at 90% thanks to the automated testing feature and the help of Moodle community members. According to an update post by Helen Foster this is the fastest QA testing for a major release ever, click here for the post:
It’s just over a week since we began our 2.5 QA cycle, and we’re up to 403 tests passed (90%), 11 tests failed (2%) and just 31 tests left to be run. A huge thank you to everyone for helping with QA testing. This cycle is the fastest ever!
