Running Tests on Chromium and Firefox with Playwright

To run tests on both Chromium and Firefox, you'll need to set up two projects in your Playwright config file.

First, import defineConfig and devices from @playwright/test.

import { defineConfig, devices } from '@playwright/test';

Next, define your projects array with two objects: one for Chromium and one for Firefox.

export default defineConfig({
  projects: [
    {
      name: 'chromium',
      use: {
        ...devices['Desktop Chrome'],
      },
    },
    {
      name: 'firefox',
      use: {
        ...devices['Desktop Firefox'],
      },
    },
  ],
});

Each project should have a unique name ('chromium' or 'firefox') and specify which device to use.

To run all projects, use the npx playwright test command. Playwright will run all projects defined in your config file by default.

If you want to run only a specific project, use the --project command line option followed by its name. For example, to run only the Chromium project, you would use npx playwright test --project chromium.
