Playwright 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
