A set of Elixir helpers to set/get test selectors to/from elements in a Phoenix app (whenMix.env == :test). These selectors are hashed (scoped to the view module they are used in) for accurate selection and "leakage" prevention. See ourWiki for examples.
Why? Because we prefer reserving classes for styling, and id's have limitations because they have to be unique.
- Floki v0.25.x and higher
