Method: Kernel#expect

Defined in:
lib/brass/expect.rb

#expect(error_class) ⇒ Object

Executate a block asserting that a type of error will be raised.

Presently this is not part of brass by default, as whether it should be is under debate. So this file must be required separately:

require 'brass/expect'
