trait Messaging[T] extends AnyRef

Supertrait for Messaging typeclasses.

Trait Messaging is a typeclass trait for objects that can be queried for message. Objects of type T for which an implicit Messaging[T] is available can be used with the should have message syntax. You can enable the have message matcher syntax on your own type U by defining a Messaging[U] for the type and making it available implicitly.

ScalaTest provides an implicit Messaging instance for java.lang.Throwable and arbitary object with message(), message, getMessage() or getMessage method in the Messaging companion object.
