Be - Behaviorial Expectations

"Oh, Behave!"

Website / Report Issue / Source Code / Mailing List

Description

Be is a fully versitle, light-weight and BRASS compliant assertions framework for Ruby. It utilizes an assertor design (matchers in RSpec terminology) which meshes well with BDD nomenclatures.

Instruction

Be's usage is very simple. It consits of using #should with a target object, and passing it the reuslt of calling #be or #have with expectation critera. Here is an example:

require 'be'

object = "string"

object.should be.instance_of?(String)
object.should have(6).size

The only difference betwee #be and #have is the default expectation method that is used if none is provided. In the base of #be it is #==, for #have it is #include?.

"abc".should be("abc")

[:a,:b,:c].should have(:b)

Be works on the principle of assertors, a type of functor, or higher-order function. In RSpec these are know as matchers. Be provides the method #should for all Objects which accepts any object that converts to an assertor via a #to_assertor method. The #be and #have method returns just that, a Be::Delegator which orgnaizes all calls made against it to use as expectations in the Be::Assertor.
