What is the role of `setup.beforeAll()` in setting up test environment in Playwright?


Sure, you can use setup.beforeAll() in @playwright/test. It's a key step in preparing your test environment. beforeAll runs before any tests are executed and is used to set up any fixtures that your tests need to run successfully.

Here's an example of how you might set up fixtures using beforeAll. You'll see that the worker setup and autoWorkerFixture setup are both done in this section because they need to be set up before anything else. This ensures that all subsequent tests have access to these fixtures.

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

test.beforeAll(async ({ browser }) => {
  // Worker setup
  const context = await browser.newContext();
  // AutoWorkerFixture setup
  const page = await context.newPage();
  await page.goto('https://ray.run/');

test('My Test', async ({ page }) => {
  // Your test code here

After beforeAll runs, the first test section begins. Here's an example of how automatic test fixtures are set up using autoTestFixture. This fixture is always set up before any tests or beforeEach hooks run.

test.beforeEach(async ({ page }) => {
  // Page fixture setup
  await page.goto('https://ray.run/');

test.afterEach(async ({ page }) => {
  // Page fixture teardown
  await page.close();

In addition to tearing down individual fixtures after each test, there's also a teardown process for all fixtures at the end of all tests. This happens in the afterAll and worker teardown section where workerFixture teardown, autoWorkerFixture teardown, and browser teardown occur.

test.afterAll(async ({ browser }) => {
  // WorkerFixture teardown
  await browser.close();

Setting up your environment correctly using setup.beforeAll() ensures that your tests run smoothly without interference from previous or subsequent tests.
