+## Testing
+JSONAPI comes with a test library to help you test your JSON API integration. The test library is called `JSONAPITestLib`. It provides literal expressibility for `Attribute`, `ToOneRelationship`, and `Id` in many situations so that you can easily write test `Entity` values into your unit tests. You can see the JSONAPITestLib in action in the Playground included with the JSONAPI repository.
