Puppeteer
Puppeteer is an open-source Node.js library developed by Google that allows developers to automate and test web browsers. It provides a high-level API to control various browser actions, such as generating screenshots, automating form submissions, and intercepting network requests. Puppeteer supports multiple browsers, including Google Chrome, Microsoft Edge, Firefox, and Safari, and allows for both headless (without a user interface) and non-headless operation. It supports a broad range of automation capabilities, including single-page applications, mobile viewport emulation, geolocation testing, and more. Puppeteer is often used in end-to-end testing to ensure that applications function correctly across different web platforms.
