Setting up the environment

What's good about Node.js and Puppeteer is that they are cross-platform. My local environment is macOS Catalina 10.15.6. But you won't see much difference if you use a Windows or a Linux environment.

That's why I encourage you to go now and take a look at the GitHub repository of this book (https://github.com/PacktPublishing/ui-testing-with-Puppeteer).
