Headless Safari Automation with Playwright: A Comprehensive Guide

Introduction

Safari is a key player in the browser ecosystem, and ensuring compatibility with it is essential for web automation and testing. However, automating Safari—especially in a headless environment—has historically been challenging. Fortunately, Playwright’s WebKit support provides a powerful way to run headless Safari automation seamlessly.

In this guide, we’ll explore how to leverage Playwright’s WebKit engine for headless Safari automation. We’ll also compare Playwright to other automation tools, benchmark its performance, and include hands-on code examples to help you get started. Plus, we’ll subtly show how BrowserCat simplifies the process.

1. Why Headless Safari Automation Matters

Safari’s unique rendering engine, WebKit, powers Apple’s ecosystem and differs significantly from Chromium and Gecko. Ensuring your web applications function correctly on Safari is crucial for cross-browser testing. Headless execution allows developers to run tests efficiently, without launching a visible browser window, making it ideal for CI/CD pipelines and automated workflows.

Key Benefits of Headless Safari Automation

• Enables cross-browser compatibility testing
• Reduces resource consumption for automated tests
• Speeds up testing in CI/CD environments
• Ensures accurate rendering on Apple devices

2. Setting Up Playwright for Safari Automation

Playwright’s WebKit mode allows developers to run tests in a Safari-like environment. Let’s get started by installing Playwright and setting up a test.

Installation

First, install Playwright and the necessary WebKit binaries:

npm install -D @playwright/test
npx playwright install webkit

Basic Playwright WebKit Script

Create a simple test to launch Safari in headless mode and navigate to a page:

const { webkit } = require('playwright');

(async () => {
    const browser = await webkit.launch({ headless: true });
    const context = await browser.newContext();
    const page = await context.newPage();
    
    await page.goto('https://browsercat.com');
    console.log(await page.title());
    
    await browser.close();
})();

This script launches a headless WebKit browser, navigates to BrowserCat’s homepage, and prints the title to verify successful execution.

3. Comparing Playwright with Selenium and Puppeteer

Feature	Playwright (WebKit)	Selenium	Puppeteer
Native WebKit Support	✅ Yes	❌ No (Uses SafariDriver)	❌ No (Chromium-only)
Headless Safari Execution	✅ Yes	✅ Yes, but limited	❌ No
Parallel Execution	✅ Yes	⚠️ Limited	✅ Yes (Chromium-only)
Built-in Test Runner	✅ Yes	❌ No	❌ No
Cross-Browser Testing	✅ Yes	✅ Yes	❌ No

Playwright offers native WebKit support, enabling Safari automation without relying on SafariDriver, as Selenium does. Compared to Puppeteer, which only supports Chromium, Playwright is the superior choice for cross-browser testing.

4. Performance Benchmarks: Speed & Reliability

When evaluating automation frameworks, execution speed and reliability are crucial. Here’s how Playwright stacks up:

• Execution Speed: Playwright’s WebKit engine is optimized for fast execution, often outperforming Selenium in headless mode.
• Stability: Unlike Selenium’s SafariDriver, Playwright does not require a separate driver process, leading to fewer failures.
• Parallel Execution: Playwright supports parallel test execution out of the box, unlike Selenium, which often requires workarounds.

These factors make Playwright the best choice for headless Safari automation.

5. Playwright Code Examples: Running Tests in Parallel

Parallel execution is essential for scaling test automation efficiently. Here’s how you can run multiple tests in parallel using Playwright’s test runner:

Configuration File

Create a Playwright configuration file:

// playwright.config.js
module.exports = {
  projects: [
    {
      name: 'webkit',
      use: { browserName: 'webkit' },
    },
  ],
};

Test File

Then, create a test file:

// tests/example.test.js
const { test, expect } = require('@playwright/test');

test('BrowserCat homepage loads successfully', async ({ page }) => {
  await page.goto('https://browsercat.com');
  await expect(page).toHaveTitle(/BrowserCat/);
});

Run Tests

Run the tests in parallel with:

npx playwright test

This approach ensures tests are executed efficiently across different browser contexts.

6. How BrowserCat Enhances Safari Automation

Managing browser automation at scale can be challenging, especially when running Playwright tests in headless mode. This is where BrowserCat comes in!

Key Benefits of Using BrowserCat with Playwright

• Cloud-Based Execution: Run Playwright tests in a distributed, cloud-based infrastructure.
• Pre-Configured Browsers: No need to manage WebKit installations manually.
• Parallel Test Execution: Speed up automation with cloud parallelization.
• Seamless Integration: Works with existing Playwright setups.

Using BrowserCat, teams can offload execution to the cloud, reducing local resource usage and increasing test reliability.
