Release Prediction Test (Analytics Snapshot Testing)
summary
Snapshot testing for analytics that compares a baseline analytics event timeline with a new one generated from the same automated UI flow, logging each event with time since test start and running as a Gradle/CI step. Implementation replaces real analytics via DI (Dagger/Hilt) to write a timeline file, then CI fails if any event is missing reordered duplicated or delayed beyond ±1 second (configurable, e.g. 0.5–1s), predicting KPI and funnel shifts at PR time.
