Just got back from Google Test Automation Conference 2011 which is probably one of the best software development conferences out there, and its free! Focus is on test automation, but the crowd is made up of a mixed bunch from across the broad spectrum of development.
Highlights for me:
Keynote from Alberto Savoia
Test is Dead (Don't take this literally, please!)
Keynote from Hugh Thompson
How hackers see bugs:
Overview of Angular and its test capabilities from Miško Hevery
All of the videos for GTAC 2011 are here:
