Selenium WebDriver

Selenium automates browsers for testing and web-based task automation. This is the official JavaScript/Node.js binding for Selenium WebDriver, version 4.44.0. It supports Chrome, Firefox, Safari, and Edge, with automatic driver management via Selenium Manager since v4.6. Releases follow Node.js LTS/Current schedule. Key differentiator: direct browser automation for end-to-end testing, unlike Playwright or Puppeteer which use DevTools Protocol; Selenium uses WebDriver W3C standard for cross-browser compatibility.
