Creating fake participants for testing purposes can be challenging, especially when coordinating multiple developers and browsers. To overcome this, automated WebDriver instances, also known as "robots," can be used to simulate users. The W3C working draft spec defines WebDriver as a remote control interface that enables introspection and control of user agents. Most browsers implement this spec, with chromedriver, safaridriver, and geckodriver being the most common examples. To spin up WebRTC-friendly headless Chromium instances locally or in the cloud, users can use various command-line options and libraries such as Selenium. Additionally, creating a custom AMI on EC2 instances can also be used to run Chromium on multiple instances. For those using Node.js, setting up a basic chromedriver-using-selenium-webdriver-npm-module setup is possible with some version matching and process management considerations.
