Documentation and fixtures are used to create a living styleguide to help develop and test your application.
See the Pen Module Example by Jason Bellamy (@jasonbellamy) on CodePen.
How does it work?
Documentation is created by prepending a name, description, category, and a fixture reference before your classes and by creating a fixture that shows how your classes should be used.
How do I structure their files & folders?
Fixtures should be placed inside of the tests/fixtures directory located at the root of each specific layout, module, unit and page folder.
