Playwright Fixtures and Hooks

Master Playwright's fixture system and lifecycle hooks to create reusable test infrastructure, manage test state, and build maintainable test suites. This skill covers built-in fixtures, custom fixtures, and best practices for test setup and teardown.

Built-in Fixtures

Core Fixtures

import { test, expect } from '@playwright/test';

test('using built-in fixtures', async ({
  page,      // Page instance
  context,   // Browser context
  browser,   // Browser instance
  request,   // API request context
}) => {
  // Each test gets fresh page and context
  await page.goto('https://example.com');
  await expect(page).toHaveTitle(/Example/);
});

Page Fixture

test('page fixture examples', async ({ page }) => {
  // Navigate
  await page.goto('https://example.com');

  // Interact
  await page.getByRole('button', { name: 'Click me' }).click();

  // Wait
  await page.waitForLoadState('networkidle');

  // Evaluate
  const title = await page.title();
  expect(title).toBe('Example Domain');
});

Context Fixture

test('context fixture examples', async ({ context, page }) => {
  // Add cookies
  await context.addCookies([
    {
      name: 'session',
      value: 'abc123',
      domain: 'example.com',
      path: '/',
    },
  ]);

  // Set permissions
  await context.grantPermissions(['geolocation']);

  // Create additional page in same context
  const page2 = await context.newPage();
  await page2.goto('https://example.com');

  // Both pages share cookies and storage
  await page.goto('https://example.com');
});

Browser Fixture

test('browser fixture examples', async ({ browser }) => {
  // Create custom context with options
  const context = await browser.newContext({
    viewport: { width: 1920, height: 1080 },
    locale: 'en-US',
    timezoneId: 'America/New_York',
    permissions: ['geolocation'],
  });

  const page = await context.newPage();
  await page.goto('https://example.com');

  await context.close();
});
