The 20 Minute Goal

Conceptual Build Templates“Quick CI”

• Optimize for shorter runtime (< 20 min)

• Run on every check-in (CI)

• Includes critical path smoke tests

• Also includes smoke tests for features related to the commit (rotate new features in and out)

• Small set of critical devices

CI Regression• Chain and run only if

Quick CI is green• Larger set of tests

and devices• Deploy to beta users

if it passes• Immediately triage if

it fails

Weekly Regression• Scheduled build

starting after everyone goes home for the weekend

• Includes all tests and all target devices

• Runtime could be very long

The Highest-Value Automated UI Test For Mobile Apps
