How do I troubleshoot a browser closing unexpectedly during a cleanup function in an automated UI test using Playwright Test?

Answer

Troubleshooting Unexpected Browser Closure

To resolve issues with the browser closing during a cleanup function in an automated UI test using @playwright/test, follow these steps:

1. Configure Cleanup Function

Ensure your cleanup function is properly configured, releasing resources and closing open connections or processes. Use a try-catch block to catch errors or exceptions:

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

test.afterEach(async ({ page }) => {
  try {
    // Your cleanup code here
  } catch (error) {
    console.error('Cleanup error:', error);
  }
});

2. Handle Timeouts

If your test takes too long, it may trigger a timeout, causing the browser to close. Increase the timeout value or optimize your test code:

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

test.setTimeout(60000); // Set the timeout to 60 seconds

test('Long running test', async ({ page }) => {
  await page.goto('https://ray.run');
  // Your test code here
});

3. Check Browser Issues

Investigate known issues with the specific browser you're using. Consider switching browsers or updating to a newer version.

4. Use Debugging Features

Utilize @playwright/test's built-in debugging features. Run tests in debug mode and step through actions while viewing logs and diagnostic information:

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

test('Debug test', async ({ page }) => {
  await page.goto('https://ray.run');
  // Your test code here
}).debug();

By following these steps, you can effectively troubleshoot and resolve issues with the browser closing unexpectedly during a cleanup function in your automated UI tests.
