Writability

Supertrait for typeclasses that enable the be writable matcher syntax.

A Writability[T] provides access to the "writable nature" of type T in such a way that be writable matcher syntax can be used with type T. A T can be any type for which the concept of being writable makes sense, such as java.io.File. ScalaTest provides implicit implementation for java.io.File. You can enable the be writable matcher syntax on your own type U by defining a Writability[U] for the type and making it available implicitly.

ScalaTest provides an implicit Writability instance for java.io.File and arbitary object with isWritable() or isWritable in the Writability companion object.
