[rspec-users] Accessing the model class from within an rspec-rails spec

[Mike Gunderloy]

Part of the testing harness on one of our projects:

module Spec::Example::ExampleGroupMethods
   def model
     self.described_type.to_s.underscore
   end

   def should_require(*attrs)
     raise "should require needs at least one attribute" if attrs.empty?
     model = model()
     attrs.each do |attribute|
       it "should require :#{attribute}" do
         m = Factory.build(model.to_sym)
         m.send("#{attribute}=", nil)
         m.should have(1).error_on(attribute)
       end
     end
   end
...
end

Using FactoryGirl for spinning up instances, but of course easily  
tweaked for other mocking.
