The Playwright Playbook — Part 3: Multi-User, Multi-Tab & Browser Context Testing

Short summary

Playwright Part 3 covers multi-user browser context testing—running simultaneous users in isolated browser contexts to test real features like notifications and permissions. It explains Playwright's architecture where each context maintains separate cookies, storage, and auth state, then builds a multi-user fixture that provides admin and user pages to tests. Includes complete DashboardPage and fixture setup for testing concurrent user interactions.

• •Multi-user testing requires isolated browser contexts, not multiple page.goto() calls
• •Each context has separate cookies, storage, and authentication state
• •Multi-user fixtures enable testing of real features: notifications, permissions, real-time collaboration
