Founder @ Screenshotbot

At Droidcon NYC 2015, I launched screenshot-tests-for-android while working for Facebook. This was the first screenshot testing library for Android, and popularized screenshot testing over the years. After leaving Facebook, I built the open-source Screenshotbot tool, a screenshot testing service, similar to internal tooling used by companies like Facebook, AirBnb and Google. I've worked with companies at different scales, each doing screenshot testing in their own unique ways.

Scaling up your Screenshot Testing, without the friction

Screenshot testing has become popular over the last few years, but most organizations limit their screenshot testing to just core design libraries, or they might disincentivize adding screenshot tests because of scaling issues. In this talk I'll give you insights into why you might have trouble scaling up your screenshot testing efforts: from flakiness, to dealing with developer friction and education, and the more obvious issues with scaling your storage for screenshots. We'll talk through potential solutions for each of these problems. We'll also show how screenshot testing can be used as a "social" tool to demonstrate the value of your testing efforts, and encouraging more testing in your team. (After all, non-engineers can understand screenshots, even if they don't understand code.) This talk generalizes to iOS and Flutter too, which hit the same scaling issues with screenshot testing.
