How do I enable the autoplay option in @playwright/test to reduce flakiness related to expected autoplay behavior?

Answer

Enabling Autoplay in @playwright/test

To enable the autoplay option in @playwright/test and reduce flakiness related to expected autoplay behavior, you can use the permissions property in the contextOptions when creating a new test context. This allows you to grant the video and audio autoplay permissions to the browser context.

Here's an example of how to enable autoplay in a test:

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

test.describe('Autoplay Test', () => {
  test.beforeEach(async ({ context }) => {
    // Grant autoplay permissions for video and audio
    await context.grantPermissions(['video', 'audio']);
  });

  test('Check if video autoplay is working', async ({ page }) => {
    await page.goto('https://ray.run/');
    const videoElement = await page.locator('video');
    const isPlaying = await videoElement.evaluate(video => !video.paused);
    expect(isPlaying).toBe(true);
  });
});

In this example, we grant the video and audio permissions to the browser context before each test. Then, we navigate to the website and check if the video element is playing as expected.

By granting the necessary permissions, you can ensure that the autoplay behavior works as intended, reducing flakiness in your tests. For more tips on writing efficient @playwright/test scripts, check out Tips for Writing Efficient Playwright Test Scripts.
