Overview

Warning expectation proxy. Used to expect warning outputs during the execution of the expect block. Warnings are matched by ignoring any trailing newlines and by removing any file/line warning prefixes. This is done as Ruby internally uses two different functions to generate warnings (rb_warn() and rb_warning()).
