## What it does

The skill fires when you ask for end-to-end tests, browser tests, integration tests, or Playwright setup. The agent works through seven steps: install Playwright, edit `playwright.config.ts`, write a smoke test that checks the page loads, add npm scripts, update `.gitignore`, and wire the run into GitHub Actions.

Setup starts with `npm init playwright@latest`, which creates `playwright.config.ts`, a `tests/` directory and downloads browsers. If the project already has a test runner, the skill installs manually instead: `npm install -D @playwright/test` followed by `npx playwright install`. The config points `baseURL` at your local dev server, and the `webServer` block starts it for you during a run. For local speed it suggests keeping chromium only and enabling every browser in CI.

Selectors should use `data-testid` rather than CSS classes. Classes change with any markup edit, so tests start failing for no real reason. Larger apps get an optional page object step with a `tests/pages/` directory. To record a scenario interactively, run `npx playwright codegen`.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill adding-e2e-tests -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/adding-e2e-tests/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/adding-e2e-tests/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill adding-e2e-tests -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/adding-e2e-tests/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill adding-e2e-tests -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/adding-e2e-tests/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills adding-e2e-tests
```

2. **Manually: put the files in place**
- File: `.github/skills/adding-e2e-tests/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill adding-e2e-tests -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/adding-e2e-tests
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/adding-e2e-tests/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill adding-e2e-tests -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/adding-e2e-tests/SKILL.md

## When to use it
- set up Playwright in a project with no tests yet
- make the dev server start automatically before a test run
- write a first smoke test that checks the page loads
- run e2e tests in GitHub Actions and keep the HTML report
- move selectors and actions into page objects for a bigger app

## Example prompts
- add Playwright e2e tests to this project
- set up playwright.config.ts with an auto-started dev server
- wire the e2e run into GitHub Actions

# Add E2E Tests (Playwright)

Use this skill when the user asks to add end-to-end tests, browser tests, integration tests, or set up Playwright.

## Steps

1. **Install Playwright**

   ```bash
   npm init playwright@latest
   ```

   This creates `playwright.config.ts`, a `tests/` directory, and installs browsers. If the project already has a test runner, install manually:

   ```bash
   npm install -D @playwright/test
   npx playwright install
   ```

2. **Configure `playwright.config.ts`**

   - Set `baseURL` to the local dev server URL (e.g. `http://localhost:3000`).
   - Configure `webServer` to start the dev server automatically:

     ```ts
     webServer: {
       command: "npm run dev",
       url: "http://localhost:3000",
       reuseExistingServer: !process.env.CI,
     },
     ```

   - Enable only chromium for local dev speed; enable all browsers in CI.

3. **Create a smoke test** — write a basic test that verifies the app loads:

   ```ts
   import { test, expect } from "@playwright/test";

   test("homepage loads", async ({ page }) => {
     await page.goto("/");
     await expect(page).toHaveTitle(/.+/);
   });
   ```

4. **Add page object pattern (optional)** — for larger apps, create a `tests/pages/` directory with page objects that encapsulate selectors and actions.

5. **Add npm scripts**

   ```json
   {
     "test:e2e": "playwright test",
     "test:e2e:ui": "playwright test --ui"
   }
   ```

6. **Add to `.gitignore`**

   ```
   test-results/
   playwright-report/
   blob-report/
   ```

7. **CI integration** — add a GitHub Actions step that runs `npx playwright install --with-deps` then `npm run test:e2e`. Use the official `actions/upload-artifact` to save the HTML report on failure.

## Notes

- Use `data-testid` attributes for selectors instead of CSS classes.
- Use `test.describe` to group related tests.
- Run `npx playwright codegen` to record tests interactively.
