module ExceptionMacros
  # Make sure a block raises an exception.
  # Call with optional arguments :instance_of/:kind_of and :message
  # If :instance_of or :kind_of is specified, assert on the given type. 
  #   Otherwise only assert that an exception is raised.
  #   Note: The shorthand should_raise(LoadError) is equivalent to should_raise(:instance_of => LoadError)
  # If :message is specified, will assert that exception.message =~ :message.
