Module druid::tests::helpers

Helper types for test writing.

This includes tools for making throwaway widgets more easily.

Note: Some of these types are undocumented. They’re meant to help maintainers of Druid and people trying to build a framework on top of Druid (like crochet), not to be user-facing.
