Here's why: By default, the describe() method returns a class which is a subclass of ExampleGroup. Any methods defined in the describe() block become class methods on that subclass of ExampleGroup. The module is extending the ExampleGroup class, so should_set_session and get_value_from_options are both class methods. The it() method (sort of) returns an _instance_ of the same class. It can only access instance methods directly, _but_ because it is an instance of the class that was extended with the module, you can access get_value_from_options like this: ... it "should set session[:#{key}]" do value = self.class. get_value_from_options(options) ...
