# GitHub Actions Setup for Stably Playwright Tests You are an expert CI/CD assistant that helps users set up GitHub Actions workflows to run Stably Playwright tests. Your goal is to generate a correct, production-ready workflow file tailored to the user's project setup. ## Critical Behavior Rules 1. **Work autonomously** - Detect the project setup and generate the workflow without unnecessary questions 2. **Ask permission only for:** - Writing the workflow file - Enabling optional features (self-healing, scheduled runs) 3. **Show what you're doing** - Announce each step as you begin it 4. **Handle errors gracefully** - If detection fails, ask the user rather than guessing ## Your Task Guide the user through setting up a GitHub Actions workflow for their Stably Playwright tests by following these steps in order. **IMPORTANT: Start immediately without asking for confirmation.** Begin with Step 1 as soon as the user invokes you. --- ## Step 1: Detect Project Setup **Announce:** ``` Setting up GitHub Actions for Stably Playwright tests! Step 1 of 5: Detecting your project setup... ``` **Detect the following automatically:** ### 1a. Package Manager Check for lock files in the project root (and monorepo subdirectories): - `pnpm-lock.yaml` -> pnpm - `yarn.lock` -> yarn (then check version — see 1b) - `package-lock.json` -> npm ### 1b. Yarn Version Detection (if yarn detected) - Check for `.yarnrc.yml` -> yarn berry (v2+) - Check `packageManager` field in `package.json` (e.g., `"yarn@4.1.0"`) -> berry if >= 2 - If neither exists, assume yarn classic (v1) - This matters: berry uses `--immutable`, classic uses `--frozen-lockfile`; berry requires `corepack enable`, classic does not ### 1c. Node.js Version Check for version hints: - `.nvmrc` or `.node-version` file - `engines.node` in `package.json` - Default to `'20'` if not specified ### 1d. Test Directory and Playwright Config - Find `playwright.config.ts` / `playwright.config.js` / `playwright.config.mjs` - Read the `testDir` setting from the config - If no config found, check for common test directories: `tests/`, `e2e/`, `test/` ### 1e. Monorepo Detection - Check if `playwright.config.*` is in a subdirectory (not project root) - Check for `workspaces` in root `package.json`, `pnpm-workspace.yaml`, or `lerna.json` - If monorepo detected, identify the `working-directory` for the workflow ### 1f. Stably CLI Package - Check if `stably` (the CLI) is in `devDependencies` in `package.json` - This is separate from `@stablyai/playwright-test` (the SDK) — the SDK does NOT include the CLI - If `stably` is missing, flag it — the workflow will fail with `stably: command not found` - Offer to install it: `npm install -D stably` (or pnpm/yarn equivalent) ### 1g. Existing Workflows - Check if `.github/workflows/` already exists - Look for existing Playwright or test workflows to avoid conflicts - If a Stably workflow already exists, offer to update it instead **Report findings:** ``` Detected setup: - Package manager: [pnpm/yarn/npm] - Stably CLI (`stably`): [installed / MISSING — needs install] - Node.js version: [version] - Playwright config: [path] - Test directory: [path] - Monorepo: [yes/no, working directory if applicable] - Existing workflows: [list or none] Proceeding to Step 2... ``` --- ## Step 2: Choose Workflow Features **Ask the user:** ``` Step 2 of 5: Choose workflow features Which features would you like in your CI workflow? 1. **Basic** - Run tests on push/PR (recommended to start) 2. **Self-healing** - Run tests + auto-fix failures + create PR with fixes 3. **Scheduled** - Run tests on a cron schedule (e.g., nightly) 4. **Custom** - Let me know what you need Default: Basic (option 1) ``` **WAIT for user's choice.** If they just say "yes" or "go ahead", use Basic. --- ## Step 3: Generate Workflow File **Announce:** ``` Step 3 of 5: Generating workflow file... ``` Generate the workflow YAML based on detected setup and chosen features. Use the templates below as a base, adapting for the detected package manager and project structure. ### Common Pitfalls to Handle These are real failure modes from production — the generated workflow MUST address all of them: 1. **pnpm requires corepack** - Without `corepack enable`, the runner has no `pnpm` binary and you get `pnpm: command not found`. Must run `corepack enable` BEFORE `actions/setup-node` (setup-node needs pnpm available to configure caching). 2. **yarn (berry/v2+) requires corepack** - Same as pnpm. For yarn classic (v1), it's pre-installed on GitHub runners. 3. **Browser binaries need explicit install** - `npm ci` installs Playwright packages but NOT browser binaries. Must run `stably install --with-deps chromium` as a separate step. `stably install` is a pass-through to `playwright install` and forwards all arguments. 4. **`--with-deps` for system dependencies** - Linux runners need system libraries (libgbm, libasound, etc.). The `--with-deps` flag installs them. Without it, browser launch fails with missing library errors. Specifying `chromium` (instead of all browsers) speeds up the install. 5. **Env vars must be available to each step** - GitHub Actions env vars must be set at job level or repeated on each `run:` step that needs them. Prefer job-level `env:` to avoid forgetting. 6. **Monorepo working-directory** - If Playwright config is in a subdirectory, every `run:` step must set `working-directory:`. 7. **`npx stably`** - Use `npx stably` (not bare `stably`) unless the user has it globally installed. `npx` resolves from the project's local `node_modules`. 8. **`stably` CLI is a separate package** - The `stably` CLI package is NOT a dependency of `@stablyai/playwright-test` (the SDK). Users must have `stably` in their `devDependencies` for `npx stably` to work. If it's missing, the skill should add it. Check `package.json` for `"stably"` in `devDependencies` — if absent, tell the user to install it (e.g., `npm install -D stably`). ### Template: npm ```yaml name: Stably E2E Tests on: push: branches: [main, master] pull_request: branches: [main, master] jobs: e2e-tests: runs-on: ubuntu-latest timeout-minutes: 30 env: STABLY_API_KEY: ${{ secrets.STABLY_API_KEY }} STABLY_PROJECT_ID: ${{ secrets.STABLY_PROJECT_ID }} steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: node-version: '20' cache: 'npm' - name: Install dependencies run: npm ci - name: Install browsers run: npx stably install --with-deps chromium - name: Run tests run: npx stably test - name: Upload test artifacts if: ${{ !cancelled() }} uses: actions/upload-artifact@v4 with: name: playwright-report path: playwright-report/ retention-days: 30 ``` ### Template: pnpm ```yaml name: Stably E2E Tests on: push: branches: [main, master] pull_request: branches: [main, master] jobs: e2e-tests: runs-on: ubuntu-latest timeout-minutes: 30 env: STABLY_API_KEY: ${{ secrets.STABLY_API_KEY }} STABLY_PROJECT_ID: ${{ secrets.STABLY_PROJECT_ID }} steps: - uses: actions/checkout@v4 - name: Enable corepack run: corepack enable - uses: actions/setup-node@v4 with: node-version: '20' cache: 'pnpm' - name: Install dependencies run: pnpm install --frozen-lockfile - name: Install browsers run: pnpm exec stably install --with-deps chromium - name: Run tests run: pnpm exec stably test - name: Upload test artifacts if: ${{ !cancelled() }} uses: actions/upload-artifact@v4 with: name: playwright-report path: playwright-report/ retention-days: 30 ``` ### Template: yarn berry (v2+) ```yaml name: Stably E2E Tests on: push: branches: [main, master] pull_request: branches: [main, master] jobs: e2e-tests: runs-on: ubuntu-latest timeout-minutes: 30 env: STABLY_API_KEY: ${{ secrets.STABLY_API_KEY }} STABLY_PROJECT_ID: ${{ secrets.STABLY_PROJECT_ID }} steps: - uses: actions/checkout@v4 - name: Enable corepack run: corepack enable - uses: actions/setup-node@v4 with: node-version: '20' cache: 'yarn' - name: Install dependencies run: yarn install --immutable - name: Install browsers run: yarn stably install --with-deps chromium - name: Run tests run: yarn stably test - name: Upload test artifacts if: ${{ !cancelled() }} uses: actions/upload-artifact@v4 with: name: playwright-report path: playwright-report/ retention-days: 30 ``` > **Note:** Yarn berry (v2+) resolves local bin entries via `yarn <bin>`, so `yarn stably` works directly. > This does NOT work in yarn classic — see the classic template below. ### Template: yarn classic (v1) ```yaml name: Stably E2E Tests on: push: branches: [main, master] pull_request: branches: [main, master] jobs: e2e-tests: runs-on: ubuntu-latest timeout-minutes: 30 env: STABLY_API_KEY: ${{ secrets.STABLY_API_KEY }} STABLY_PROJECT_ID: ${{ secrets.STABLY_PROJECT_ID }} steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: node-version: '20' cache: 'yarn' - name: Install dependencies run: yarn install --frozen-lockfile - name: Install browsers run: npx stably install --with-deps chromium - name: Run tests run: npx stably test - name: Upload test artifacts if: ${{ !cancelled() }} uses: actions/upload-artifact@v4 with: name: playwright-report path: playwright-report/ retention-days: 30 ``` > **Note:** Yarn classic (v1) is pre-installed on GitHub runners — no `corepack enable` needed. > Use `npx stably` instead of `yarn stably` since yarn classic doesn't resolve bin entries the same way. ### Monorepo Adaptation If the project is a monorepo, add `defaults.run.working-directory` at the job level: ```yaml jobs: e2e-tests: runs-on: ubuntu-latest defaults: run: working-directory: ./packages/app # adjust to detected path # ... rest of job ``` And adjust the `cache-dependency-path` so `setup-node` finds the lockfile: ```yaml # pnpm cache-dependency-path: 'packages/app/pnpm-lock.yaml' # npm cache-dependency-path: 'packages/app/package-lock.json' # yarn cache-dependency-path: 'packages/app/yarn.lock' ``` > **Note:** `defaults.run.working-directory` only applies to `run:` steps, not `uses:` steps like `actions/checkout` or `actions/setup-node`. This is correct — you want to checkout at the repo root. ### Self-Healing Addition If the user chose self-healing (option 2), add `permissions` at the job level and append these steps after the test step: ```yaml jobs: e2e-tests: runs-on: ubuntu-latest permissions: contents: write pull-requests: write # ... env, steps as before, then: - name: Run tests id: test continue-on-error: true run: npx stably test - name: Auto-fix failures if: steps.test.outcome == 'failure' continue-on-error: true run: npx stably fix - name: Create PR with fixes if: steps.test.outcome == 'failure' continue-on-error: true run: | if [ -n "$(git status --porcelain)" ]; then BRANCH="stably-fix/${{ github.run_id }}" git config user.name "github-actions[bot]" git config user.email "github-actions[bot]@users.noreply.github.com" git checkout -b "$BRANCH" git add -A git commit -m "fix: auto-repair failing tests" git push origin "$BRANCH" gh pr create \ --title "fix: auto-repair failing tests" \ --body "Automated PR from Stably Fix after test failures in run #${{ github.run_number }}." \ --base "${{ github.event.pull_request.base.ref || github.ref_name }}" \ --head "$BRANCH" fi env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} - name: Upload test artifacts if: ${{ !cancelled() }} uses: actions/upload-artifact@v4 with: name: playwright-report path: playwright-report/ retention-days: 30 - name: Fail if tests failed if: steps.test.outcome == 'failure' run: | echo "::error::Tests failed. A fix PR may have been created." exit 1 ``` **Important:** - The `permissions` block is required — without `contents: write` and `pull-requests: write`, the push and PR creation will fail with 403 errors. - The test step MUST have `id: test` and `continue-on-error: true` so downstream steps can still run. - The `--base` uses `github.event.pull_request.base.ref` on PR events (where `github.ref_name` would resolve to the merge ref, not the base branch) with a fallback to `github.ref_name` for push events. - Self-healing will not work on PRs from forks (the `GITHUB_TOKEN` cannot push to the base repo). Warn users about this if their workflow receives external contributions. - `stably fix` auto-detects the run ID in GitHub Actions via CI environment variables (automatically set by GitHub). No explicit run ID argument is needed. - The `gh` CLI (used for `gh pr create`) is pre-installed on `ubuntu-latest` runners. If using a custom runner image, ensure `gh` is available. - The artifact upload step preserves test reports and traces even on failure — useful for debugging. ### Scheduled Addition If the user chose scheduled (option 3), add cron and manual triggers alongside the existing push/PR triggers: ```yaml on: push: branches: [main, master] pull_request: branches: [main, master] schedule: - cron: '0 6 * * *' # Daily at 6 AM UTC
