- buildMcpArgs: use CI env var instead of token detection (preserves local behavior)
- browser.test.ts: align tests with CI-based mode detection
- api-health.test.ts: remove duplicate xueqiu entry
- browser-public.test.ts: unify BBC test with tryBrowserCommand
- vitest.config.ts: default to unit tests only (E2E via explicit path)
- ci.yml: remove unnecessary needs:build for unit-test, use composite action
- e2e-headed.yml: use composite action, increase timeout to 20min
- Add .github/actions/setup-chrome composite action for shared CI steps
# feat: add E2E testing infrastructure with real Chrome in CI
## What
Establish a comprehensive E2E testing framework for opencli using **real Chrome + xvfb virtual display** in GitHub Actions CI.
## Changes
### E2E Test Suite (~52 test cases)
- `public-commands.test.ts` — Public API commands (hackernews, v2ex)
- `browser-public.test.ts` — Browser commands for public data across all 18 sites (21 tests)
- `browser-auth.test.ts` — Graceful failure verification for login-required commands (14 tests)
- `management.test.ts` — Full coverage of management commands (list/validate/verify/version/help)
- `output-formats.test.ts` — Output format validation (json/yaml/csv/md)
- `smoke/api-health.test.ts` — Scheduled API health checks
### Auto-detect Browser Mode
- `buildMcpArgs` automatically selects mode based on `PLAYWRIGHT_MCP_EXTENSION_TOKEN`:
- Token present → `--extension` (local user, connects to logged-in Chrome)
- Token absent → standalone (CI launches its own browser)
- No extra environment variables needed
### CI Pipeline
- `e2e-headed.yml` — Real Chrome via `browser-actions/setup-chrome` + `xvfb-run` in headed mode
- `ci.yml` — build + unit-test (2 shards) + smoke-test (scheduled/manual)
- Browser commands that return empty data due to geo-blocking or bot detection gracefully warn + pass without blocking CI
### Documentation
- New `TESTING.md` — Architecture, coverage, local setup, how to add tests, CI explanation
- Updated `README.md` — Added Testing section with quick-start commands
