Cypress & Playwright Setup

Configure comprehensive end-to-end testing for web applications.

Core Workflow

  1. Choose tool: Cypress or Playwright
  2. Configure project: Browser and test settings
  3. Create page objects: Reusable selectors
  4. Write tests: User journey coverage
  5. Setup fixtures: Test data
  6. Integrate CI: Automated testing

Playwright Setup

Installation

Accessibility Testing

// e2e/accessibility.spec.ts (Playwright)
import { test, expect } from '@playwright/test';
import AxeBuilder from '@axe-core/playwright';

test.describe('Accessibility', () => {
  test('homepage has no accessibility violations', async ({ page }) => {
    await page.goto('/');

    const accessibilityScanResults = await new AxeBuilder({ page }).analyze();

    expect(accessibilityScanResults.violations).toEqual([]);
  });

  test('login page has no accessibility violations', async ({ page }) => {
    await page.goto('/login');

    const accessibilityScanResults = await new AxeBuilder({ page })
      .withTags(['wcag2a', 'wcag2aa'])
      .analyze();

    expect(accessibilityScanResults.violations).toEqual([]);
  });
});
// cypress/e2e/accessibility.cy.ts
import 'cypress-axe';

describe('Accessibility', () => {
  beforeEach(() => {
    cy.injectAxe();
  });

  it('homepage has no accessibility violations', () => {
    cy.visit('/');
    cy.checkA11y();
  });

  it('login form is accessible', () => {
    cy.visit('/login');
    cy.checkA11y('[data-testid="login-form"]');
  });
});

Best Practices

  1. Use page objects: Maintainable selectors
  2. Use test IDs: Stable element selection
  3. Avoid sleep: Use proper waits
  4. Isolate tests: No dependencies between tests
  5. Mock external APIs: Reliable, fast tests
  6. Test accessibility: Include a11y checks
  7. Parallel execution: Faster CI
  8. Meaningful assertions: Clear expectations

Output Checklist

Every E2E setup should include:

  • Playwright/Cypress configuration
  • Page object model
  • Custom commands/fixtures
  • API mocking setup
  • Authentication handling
  • Multi-browser testing
  • Accessibility tests
  • CI integration
  • Reporting configuration
  • Screenshot/video on failure
