Terra Toolkit is a utility module used to facilitate independent development of Terra projects. This toolkit provides build scripts, configurations, and Webdriver Services needed to serve assets, compile webpack, and run webdriver.io tests to streamline development of npm packages. terra-core, terra-clinical, and terra-framework are a few examples repos which are utilizing the utilities offered in this package, while terra-dev-site is a repo that extends the configurations offered by toolkit. Terra Toolkit uses Docker to setup, run, and tear down selenium to ensure a consistent testing environment locally and in continuous integration build systems. To use Terra Toolkit for webdriver testing, you must install docker on your machine.
