Initialize Playwright Project¶
Set up a production-ready Playwright testing environment. Detect the framework, generate config, folder structure, example test, and CI workflow.
Steps¶
1. Analyze the Project¶
Use the Explore subagent to scan the project:
- Check
package.jsonfor framework (React, Next.js, Vue, Angular, Svelte) - Check for
tsconfig.json→ use TypeScript; otherwise JavaScript - Check if Playwright is already installed (
@playwright/testin dependencies) - Check for existing test directories (
tests/,e2e/,__tests__/) - Check for existing CI config (
.github/workflows/,.gitlab-ci.yml)
2. Install Playwright¶
If not already installed:
Or if the user prefers manual setup:
3. Generate playwright.config.ts¶
Adapt to the detected framework:
Next.js:
import { defineConfig, devices } from '@playwright/test';
export default defineConfig({
testDir: './e2e',
fullyParallel: true,
forbidOnly: !!process.env.CI,
retries: process.env.CI ? 2 : 0,
workers: process.env.CI ? 1 : undefined,
reporter: [
['html', { open: 'never' }],
['list'],
],
use: {
baseURL: 'http://localhost:3000',
trace: 'on-first-retry',
screenshot: 'only-on-failure',
},
projects: [
{ name: "chromium", use: { ...devices['Desktop Chrome'] } },
{ name: "firefox", use: { ...devices['Desktop Firefox'] } },
{ name: "webkit", use: { ...devices['Desktop Safari'] } },
],
webServer: {
command: 'npm run dev',
url: 'http://localhost:3000',
reuseExistingServer: !process.env.CI,
},
});
React (Vite):
- Change baseURL to http://localhost:5173
- Change webServer.command to npm run dev
Vue/Nuxt:
- Change baseURL to http://localhost:3000
- Change webServer.command to npm run dev
Angular:
- Change baseURL to http://localhost:4200
- Change webServer.command to npm run start
No framework detected:
- Omit webServer block
- Set baseURL from user input or leave as placeholder
4. Create Folder Structure¶
e2e/
├── fixtures/
│ └── index.ts # Custom fixtures
├── pages/
│ └── .gitkeep # Page object models
├── test-data/
│ └── .gitkeep # Test data files
└── example.spec.ts # First example test
5. Generate Example Test¶
import { test, expect } from '@playwright/test';
test.describe('Homepage', () => {
test('should load successfully', async ({ page }) => {
await page.goto('/');
await expect(page).toHaveTitle(/.+/);
});
test('should have visible navigation', async ({ page }) => {
await page.goto('/');
await expect(page.getByRole('navigation')).toBeVisible();
});
});
6. Generate CI Workflow¶
If .github/workflows/ exists, create playwright.yml:
name: "playwright-tests"
on:
push:
branches: [main, dev]
pull_request:
branches: [main, dev]
jobs:
test:
timeout-minutes: 60
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: lts/*
- name: "install-dependencies"
run: npm ci
- name: "install-playwright-browsers"
run: npx playwright install --with-deps
- name: "run-playwright-tests"
run: npx playwright test
- uses: actions/upload-artifact@v4
if: ${{ !cancelled() }}
with:
name: "playwright-report"
path: playwright-report/
retention-days: 30
If .gitlab-ci.yml exists, add a Playwright stage instead.
7. Update .gitignore¶
Append if not already present:
8. Add npm Scripts¶
Add to package.json scripts:
{
"test:e2e": "playwright test",
"test:e2e:ui": "playwright test --ui",
"test:e2e:debug": "playwright test --debug"
}
9. Verify Setup¶
Run the example test:
Report the result. If it fails, diagnose and fix before completing.
Output¶
Confirm what was created:
- Config file path and key settings
- Test directory and example test
- CI workflow (if applicable)
- npm scripts added
