What is the process to set up projects in the config file for testing different browser versions using Playwright?

Answer

Setting Up Projects in the Config File

To set up projects in the config file for testing different browser versions using Playwright, follow these steps:

1. Create a configuration file: Create a playwright.config.ts file in your project's root directory.

2. Define projects: In the config file, define multiple projects with specific names like "chromium", "firefox", "webkit", "Mobile Chrome", "Mobile Safari", "Google Chrome", and "Microsoft Edge". For each project, specify the browser type, browser version, and any additional options such as mobile viewports or branded browsers.

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

const config: PlaywrightTestConfig = {
  projects: [
    {
      name: 'chromium',
      use: { browserName: 'chromium' },
    },
    {
      name: 'firefox',
      use: { browserName: 'firefox' },
    },
    {
      name: 'webkit',
      use: { browserName: 'webkit' },
    },
    {
      name: 'Mobile Chrome',
      use: {
        browserName: 'chromium',
        viewport: { width: 375, height: 667 },
      },
    },
    {
      name: 'Mobile Safari',
      use: {
        browserName: 'webkit',
        viewport: { width: 375, height: 667 },
      },
    },
    {
      name: 'Google Chrome',
      use: {
        browserName: 'chromium',
        channel: 'chrome',
      },
    },
    {
      name: 'Microsoft Edge',
      use: {
        browserName: 'chromium',
        channel: 'msedge',
      },
    },
  ],
};

export default config;

3. Run tests: Use the --project command line option to run a single project or use npx playwright test to run all projects by default.

npx playwright test --project chromium

By following these steps, you can set up projects in your config file for testing different browser versions using Playwright. This allows you to run tests on various browsers and configurations, ensuring your application works as expected across different environments.
