Sharing Authentication State | Bondar Academy

Lesson Summary

This lesson introduces a powerful feature in Playwright that allows for sharing authentication state across tests. This feature enables you to authenticate once, and Playwright will automatically inject this authenticated state into subsequent tests, significantly reducing the need to log in repeatedly. Configuration Steps To set up this feature, follow these steps: Create a folder: Create a folder named playwright.auth to store the session file. Update .gitignore: Add the new folder to your .gitignore to prevent sensitive data from being committed to version control. Create auth.setup.ts: Under the test folder, create a file named auth.setup.ts and modify it based on the Playwright documentation. Install TypeScript definitions: If you encounter issues, install the necessary TypeScript definitions and configure your tsconfig.json file to include node types. Implement login flow: Replace the example login flow in auth.setup.ts with your application's login steps. Validate login: Ensure the application is fully loaded before capturing the session state. Capture state: Use page.context.storageState() to write the authenticated state to user.json . Project Configuration In the playwright-config.ts file: Create a new project for the setup file. Add the storage state path to other projects to ensure they use the authenticated state. Establish dependencies between projects to maintain execution order. Once configured, you can run your tests without needing to log in each time. Playwright will handle the authentication state automatically, allowing for a smoother testing experience. This feature is particularly useful as it adapts to various identity management providers, ensuring that the necessary information is captured for each application.
