Handling Timing Issues with Playwright's Auto-Waiting Feature

Playwright's auto-waiting feature is your best friend when it comes to handling timing issues in your tests. It performs a series of checks on elements before any action is taken, ensuring that everything behaves as expected.

Here's what Playwright checks for:

• The element is attached to the DOM
• The element is visible
• The element is stable (not animating or has completed animation)
• The element can receive events (not obscured by other elements)
• The element is enabled

You can also set custom timeouts for retry intervals when making assertions. Here's an example using the expect() function with a custom timeout:

await expect(async () => { 
  const response = await page.request.get('https://ray.run'); 
  expect(response.status()).toBe(200); 
}).toPass({ 
  intervals: [1_000, 2_000, 10_000],
  timeout: 60_000
});

This allows you to control how long your test waits between retries when checking for certain conditions or responses.

If your test fails due to an assertion error or other timing-related issue, Playwright offers several tools to help you troubleshoot. Soft assertions let you make multiple checks without immediately ending the test, and the trace viewer gives you detailed info about each step of your test execution.

By using these features, you can make your tests more reliable and accurate. Happy testing with Playwright!
