Run Playwright tests on Azure Playwright Testing (Playwright Workspaces) to parallelise across cloud browsers

Steps

1. Create a Playwright Workspace in the Azure portal under Azure App Testing and copy the regional service endpoint URL
2. Install the service package: npm install @azure/microsoft-playwright-testing
3. Add a playwright.service.config.ts that imports from @azure/microsoft-playwright-testing and passes the endpoint URL and authentication (DefaultAzureCredential or access token)
4. Run tests with the service config: npx playwright test --config=playwright.service.config.ts --workers=20 to distribute across up to 50 cloud-hosted browsers
5. View test results, traces, and screenshots in the Azure App Testing portal under your Workspace
6. Integrate into CI by setting the PLAYWRIGHT_SERVICE_URL environment variable and using the service config file in your pipeline command
