Shoulda not working in Padrino, fails with undefined method `delegate'

Question

I've recently set up a couple of Padrino projects and each time I generated the project, I used Shoulda as the test option. But when I try to run 'padrino rake test,' it fails with the following error:

Sonnys-MacBook-Pro:sample_blog sonnyjitsu$ padrino rake test
=> Executing Rake test ...

Answer 1

I've not tried to use shoulda-matchers outside of rails before, but it looks like they make use of the delegate macro provided by ActiveSupport. Try require 'activesupport' (or a more limited subset if you'd rather) in your tests to see if that helps.

Answer 2

require 'active_support/core_ext/module/delegation'

worked for me
