# Include this module wherever you need to be able to make a quick,
# low-ceremony assertion.
module Assertion
protected
# Provides a mechanism to make assertions about the state of your
# UIComponent without relying on a specific testing framework. A good
# reason to use this would be to provide a more informative error message
# when a pre-condition is not met, rather than waiting on an operation
# further down the line to fail.
#
# @param [boolean expression] test an expression that will be evaluated in a boolean context
# @param [String] message the exception message that will be used if
# test is false
#
# @raise [Kookaburra::AssertionFailed] raised if test evaluates to false
def assert(test, message = "You might want to provide a better message, eh?")
test or raise AssertionFailed, message
