trait ValueMapping[-M] extends AnyRef

Supertrait for typeclasses that enable contain value matcher syntax.

A ValueMapping[M] provides access to the "value mapping nature" of type M in such a way that contain value matcher syntax can be used with type M. An M can be any type for which contain value syntax makes sense. ScalaTest provides implicit implementations for scala.collection.GenMap and java.util.Map. You can enable the contain value matcher syntax on your own type U by defining a ValueMapping[U] for the type and making it available implicitly.

ScalaTest provides implicit ValueMapping instances for scala.collection.GenMap, and java.util.Map in the ValueMapping companion object.
