How do I use Playwright in TypeScript to check the status of an API response within a certain time limit?


Sure, let's dive into how you can monitor API response time with Playwright in TypeScript.

First, you need to import the expect function from @playwright/test.

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

Then, use the expect function with an async arrow function to make the API request and check its response status. You can set custom timeout intervals for retrying the assertion with the toPass method.

await expect(async () => {
  const response = await page.request.get('https://ray.run');
  intervals: [1000, 2000, 10000],
  timeout: 60000

In this example, Playwright will retry the assertion at intervals of 1000, 2000, and 10000 milliseconds until it passes or the 60-second timeout is reached.

This approach lets you ensure your API calls respond within acceptable limits. If an assertion fails or times out during any interval within the timeout period, an error is thrown.
