We’re off to a great start, with some awesome contributors already writing lots of great testcases. So, if you haven’t already done so, head over to the wiki page for all the details. Help us make the Lightning/Sunbird Quality Assurance story as solid as it can be!
Update: Due to the overwhelming response (you guys rock!), we’re extending the testcase-writing day for another 24hrs. Note that because the lead developers do need to sleep, there may not always be someone in #calendar-qa immediately ready to answer your questions, but we’ll be as responsive as possible.
