iOS Testing on Scale
summary
30,000 automated tests today and a 50,000-test target next year, with unit tests mandatory and UI suites split into smoke, snapshot and regression that run from Jenkins using a single uploaded build on an internal file server. Built tools include CVT kit (mirroring-based unit helper that cuts test time ~40%), a custom mock server replacing Swifter, modified molo mock generator, a Python image diff and snapshot dashboard, a test planner that mutes failing tests to save >25 minutes and cut runtimes up to 80%.
