Summit producer highlights:

Learn more about the CI team behind one of the largest Android application teams on the planet. Inez shares Block’s techniques for UI test avoidance. This includes decompiling the apk/test apks and taking hash of those, and when they determine that they already tested those combinations, they skip the UI tests. This technique minimizes the set of CI shards that need to run and resulted in 50% of shards skipped.
