 In order for the plugin or package to use Jest, a jest.config.js file must be present in it's root. However, there are safeguards for this in CI should a test file be added without a corresponding config file.

+The majority of this logic is extracted from the legacy grunt build, and is designed to maintain the general structure grunt provides including tasks and config. The [build_distributables.js] file defines which tasks are run.
 
 **Task**: [tasks/\*] define individual parts of the build. Each task is an object with a `run()` method, a `description` property, and optionally a `global` property. They are executed with the runner either once (if they are global) or once for each build. Non-global/local tasks are called once for each build, meaning they will be called twice be default, once for the OSS build and once for the default build and receive a build object as the third argument to `run()` which can be used to determine paths and properties for that build.
