⚡ Playwright Performance Bottleneck Solved: How do you implement an efficient and robust authentication strategy in Playwright for E2E tests, minimizing setup time and ensuring reliability across test runs? 📌 Problem Statement Many E2E test suites suffer from slow execution and flakiness due to repetitive login flows. ❌ Running full UI login steps before every test suite or spec significantly increases test duration. ❌ UI interactions for login can be unstable, leading to unreliable tests that fail intermittently. The goal is to authenticate once and reuse the session efficiently. 💡 Solution & Code Walkthrough Playwright offers browserContext.storageState() combined with global-setup to create a reusable authentication state. This approach captures cookies, local storage, and session storage after a successful login, allowing subsequent tests to start with an authenticated session. • Step 1: Configure global-setup in playwright.config.ts Define a setup file that ru
