Screencast RubyTapas: Testing Blocks Ruby

Today's episode answers the question: How do you test that a block passed to a method is executed as intended? We could raise an exception or output a warning, but Avdi shows us a better way using a probe variable along with descriptive symbols to test whether or not the expected yield has occured.

Avdi is the creator of RubyTapas, a twice-weekly screencast series covering a wide variety of intermediate to advanced Ruby concepts and techniques, as well as core Object-Oriented design principles.
