What is the process of injecting configurations in Playwright Test similar to Cypress using webpack preprocessor?


Injecting Configurations in Playwright Test

To inject configurations in Playwright Test, you can create a configuration matrix. This matrix defines different combinations of devices or browsers for your tests. It's a centralized way to manage configurations, saving you time and effort.

Here's how you can get started:

  1. Install the Playwright library in your Node.js project using npm or Yarn.
  2. Require Playwright in your Node.js script and launch any of the supported browsers (Chromium, Firefox, or WebKit).
import { chromium } from '@playwright/test';

const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto('https://ray.run/');
await browser.close();

Playwright APIs are asynchronous and return Promise objects. Use the async/await pattern for better readability.

For project-specific configurations, there's currently no direct support for reusing an existing Vite config within Playwright Test. However, you can copy relevant settings from your existing Vite config into the ctViteConfig property of the Playwright config object.

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

test('my test', async ({ page }) => {
  await page.goto('https://ray.run/');
  const name = await page.innerText('.name');

Remember, while copying path mappings and high-level settings might be possible, there may be other aspects of your Vite config that cannot be reused directly.
