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