Ci

Playwright CI/CD

Ship reliable tests in every pipeline — CI-specific patterns for speed, stability, and actionable reports.

9 guides covering CI/CD setup, parallel execution, containerized runs, reporting, and infrastructure patterns for all major CI providers.

Golden Rules

1. retries: 2 in CI only — surface flakiness in pipelines, not locally
2. traces: 'on-first-retry' — capture rich debugging artifacts without slowing every run
3. Shard across runners — --shard=N/M splits tests evenly; scale horizontally, not vertically
4. Cache browser binaries — ~/.cache/ms-playwright keyed on Playwright version
5. Upload artifacts on failure — traces, screenshots, and HTML reports as CI artifacts
6. Use the official Docker image — mcr.microsoft.com/playwright:v* has all OS deps pre-installed
7. Global setup for auth — run login once in globalSetup, reuse storageState across workers
8. Fail fast, debug later — keep CI runs short; use trace viewer and HTML reports to investigate
