| Pitfall | Solution | |---------|----------| | Over-reliance on static delays | Use waitFor conditions instead of sleep() . | | Scripts that work locally but fail in CI | Dockerize your environment; use same browser version. | | Ignoring network conditions | Mock slow responses with route.fulfill( delay: 1000 ) . | | Testing too much in one script | Keep each replay script focused on one user journey. | | No maintenance of selectors | Create a centralized selector map or use data-testid . | FE Replay Script

Unlike generic unit tests that mock DOM events, an FE Replay Script operates in a real or headless browser environment. It simulates genuine user behavior: clicking buttons, typing into input fields, checking radio boxes, waiting for async responses, and submitting forms. | Technology | Role in FE Replay Script

// Wait 1 sec – message should stay, but it disappears await page.waitForTimeout(1000); await expect(errorMessage).not.toBeVisible(); // Fails in fixed version

The front-end ecosystem changes daily—new frameworks, updated libraries, shifting designs. Without an automated safety net, you’re constantly flying blind. An is not just a testing tool; it’s a record of how real humans interact with your product. | | Selenium WebDriver | Legacy enterprise compatibility
