How about a forum focused on the issues around automated testing of ext-js apps?
This would be a place where folks can share their experiences w/ Selenium, Jasmine, etc.
...and a good place to identify known hurdles, workarounds, etc.
(Here's why i ask... i'm helping a team now w/ selenium testing, and we're running into issues where the ext-js app _is_ using IDs for the components, but these do not appear in the rendered dom. Specific current issue is TabPanel tabs. Anyhow... i'm digging into ~why~ the ID value is missing from the markup.. but it would be useful if there was a place to find (and more importantly record, share, and discuss) known issues w/ automated testing.)
