User Testing

Speaker: Raphael Michel [e-mail]

Inspirational book: Steve Krug: Don't make me think

Tools

• Testfairy

• Google Analytics for A/B tests in your real app

• Play Store/Google+ for beta testing

Methodology

• Record user sessions using a video camera (better than screen sharing on mobile devices)

• 5 users catch enough bugs to fix in a while

• Hallway testing -- ask random strangers

• offer bug bounties and easy feedback channels

• people get bug-blind if they test the same app too often

• A/B tests

• Eye tracking to detect where users get stuck

• Test early in the design process, even on sketches only

• Test with users that are used to other platforms as well (i.e. iOS users)
