Puppeteer can do most of the things you can do in the browser. Puppeteer core is a lightweight version Puppeteer that can be used to launch an existing browser or to connect to a remote one. Make sure the puppeteer-core version you install is compatible to the browser you want to connect to. People who have used other browser testing frameworks will be familiar with Puppeteer. You create a Browser instance, open pages, then use Puppeteer's API to manipulate them. Puppeteer automatically downloads and uses a particular version of Chromium to ensure that its API works right out of the box. When creating a Browser instance, pass the executable's path to Puppeteer.
