🧪 Why Choose Browser Swarm for Automated Testing?

• Consistent Environments: Run tests in isolated, predictable browser instances to minimize flaky results.

• Scalability: Execute multiple tests concurrently to accelerate the testing process.

• Framework Compatibility: Integrate seamlessly with popular testing frameworks like Playwright, Puppeteer, and Selenium.

• Advanced Features: Utilize stealth mode, proxy integration, and session replay for comprehensive testing scenarios.

• Real-Time Monitoring: Observe test executions live and debug issues promptly.

⚙️ Setting Up Automated Tests

1. Initialize a Browser Session

Begin by creating a browser session using the Browser Swarm SDK or API. Configure the session with desired settings such as browser type, viewport size, and proxy usage.

2. Integrate with Testing Frameworks

Leverage your preferred testing framework to define and execute test cases. Browser Swarm supports integration with:

• Playwright: For modern, cross-browser testing with powerful automation capabilities.

• Puppeteer: Ideal for Chromium-based browser automation.

• Selenium: A versatile framework supporting multiple programming languages and browsers.

3. Execute Test Cases

Run your test suites against the browser sessions. Utilize Browser Swarm's features like stealth mode to mimic real user behavior and avoid detection.

4. Monitor and Debug

Use the real-time monitoring dashboard to observe test executions. In case of failures, access session replays and logs to diagnose and resolve issues efficiently.

🧾 Sample Test: Login Flow with Playwright

Here's an example of automating a login test using Playwright with Browser Swarm:

import { chromium } from 'playwright-core';
import { BrowserSwarm } from 'browser-swarm-sdk';

const bs = new BrowserSwarm({ apiKey: process.env.BROWSER_SWARM_API_KEY });

(async () => {
  const session = await bs.sessions.create({
    projectId: process.env.BROWSER_SWARM_PROJECT_ID,
    stealth: true
  });

  const browser = await chromium.connectOverCDP(session.connectUrl);
  const context = browser.contexts()[0];
  const page = context.pages()[0];

  await page.goto('https://example.com/login');
  await page.fill('#username', 'testuser');
  await page.fill('#password', 'securepassword');
  await page.click('#login-button');

  // Add assertions to verify successful login

  await browser.close();
})();

This script demonstrates launching a browser session, navigating to a login page, entering credentials, and submitting the form. You can expand upon this by adding assertions to validate successful login and other post-login behaviors.

💡 Best Practices

• Use Stable Selectors: Prefer unique identifiers like IDs or data attributes to locate elements reliably.

• Implement Wait Strategies: Ensure elements are ready before interacting to avoid flaky tests.

• Isolate Tests: Design tests to be independent to facilitate parallel execution and easier debugging.

• Leverage Session Replays: Utilize session recordings to analyze failures and improve test reliability.

• Maintain Test Data: Use consistent and controlled test data to ensure predictable outcomes.
