This is probably the most commonly used setup. Selenium: here we install Selenium with Node.js and Chrome.This will install Puppeteer, and download a recent version of Chromium that is guaranteed to work with Puppeteer. Puppeteer: assuming Node.js is installed, setting up Puppeteer is straight forward: just run npm install puppeteer.It can be used with Chrome or Chromium (which forms the basis of Chrome). It was developed by Google for the purpose of automating and simplifying front-end tests and development. Puppeteer: Puppeteer is much newer (first released in 2017).It supports a wide range of browsers (Chrome, Firefox, Safari …), and a wide range of programming languages (Java, C#, Python, Ruby …) Selenium: Selenium has been around the longest (since 2004), and has established itself as the most popular web browser automation tool.In this blog, through experimentation, I compare the two most popular browser automation frameworks, focusing on the two points mentioned above (speed and stability): Selecting the most suitable tool contributes to browser automation project success. The graph below shows the most popular ones (based on the number of downloads) in the last 18 months: ![]() ![]() There are a few Node.js frameworks capable of controlling a browser. The main component needed to write browser automated checks is a browser controller: a tool that simulates user actions. If a test suite shows false negatives very often then real issues might slip through as the team may assume that a failure is a false negative when it is a real defect. False negatives confuse the team, and need time and effort to investigate.
