Adaptation of the E2E Tests for a Big Project
summary
DeliveryHero adapts end-to-end testing for a large codebase by building a separate tests repo, running tests as a cron job today while migrating into CI/CD, and integrating a custom Cypress integration that produces Slack reports with stack traces and screenshots. Teams of ~20 front-end engineers submit ~10 PRs daily across microfrontends (50k LOC) and a monolith (200k LOC). Utilities include a goDirect command that seeds localStorage to skip flows and a cookie-based feature variation service to exercise flag permutations; work is already reducing manual regression effort.
