rails 3 initialize module, running cucumber

I have this in my environment file, I get “The error occurred while evaluating nil. (NoMethodError)” on the S3Config.key= line when running cucumber. Why is it not loading up the module when running cucumber?

module S3Config mattr_accessor :key mattr_accessor :sec end

class ActiveRecord::Base include S3Config extend DynamicMethods end

S3Config.key = AppConfig[‘access_key_id’] S3Config.sec = AppConfig[‘secret_access_key’] ActionMailer::Base.default_url_options[:host]=AppConfig[‘base_url’]
