How do I set up worker fixtures in Playwright Test for testing different access levels?


To test different access levels using worker fixtures in @playwright/test, follow these steps:

  1. Set up services and run servers in the worker process: Worker fixtures are set up for each worker process, allowing you to run servers and set up services.

  2. Generate unique accounts: Use workerInfo.workerIndex in your test or fixture to create unique accounts for testing access levels.

  3. Authenticate once per worker: Use a worker-scoped fixture, such as workerStorageState, to authenticate once per worker. This asynchronous function takes an object containing context information and a callback function called use.

  4. Create and store authentication state: If there's no stored authentication state data, create one by acquiring a unique account and sending an authentication request. Store the new context into a .auth/${id}.json file using await context.storageState({ path: fileName }).

  5. Dispose of the new context: Before calling the callback function again with updated arguments, dispose of the new context.

Here's a TypeScript code example:

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

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

By following these steps, you can effectively use worker fixtures in Playwright Test to test different access levels in your project. Make sure to create unique accounts to avoid interference when multiple team members run tests simultaneously.
