E2E Testing
End-to-end testing with Playwright and Cypress.
Tool Choice
| Factor | Playwright | Cypress |
|---|---|---|
| Language | JS/TS, Python, C#, Java | JS/TS only |
| Browser support | Chromium, Firefox, WebKit | Chromium, Firefox, WebKit |
| Iframe support | Native | Limited |
| Network mocking | Route API | intercept() |
| Parallel execution | Built-in | Dashboard required |
Playwright Patterns
Selector Strategy (Priority Order)
getByRole()— best for accessibilitygetByText()— for text contentgetByTestId()— for complex componentsgetByLabel()— for form fieldslocator(CSS)— last resort
Test Structure
test.describe('Checkout Flow', () => {
test('completes purchase with valid card', async ({ page }) => {
await page.goto('/products');
await page.getByText('Add to Cart').first().click();
await page.getByRole('button', { name: 'Checkout' }).click();
await page.getByLabel('Card Number').fill('4242424242424242');
await page.getByRole('button', { name: 'Pay' }).click();
await expect(page.getByText('Thank you')).toBeVisible();
});
});
Visual Testing
- Use
await expect(page).toHaveScreenshot() - Maintain baseline screenshots in version control
- Run visual tests on CI with 1% threshold
- Use percy.io or Chromatic for cloud-based visual review
