Framework Overview: Architecture & Core Differences

Understanding the fundamental architecture of each framework is crucial for AI testing success. Playwright runs directly in the browser process, providing native access to browser APIs. Cypress executes in the same run loop as your application, offering real-time debugging but limiting cross-origin testing. Selenium uses WebDriver protocol, creating a bridge between test code and browser, which adds latency but provides broader browser support.
