So you're getting an error message like the following, although your Gemfile lists shoulda-matchers
and it has always worked:
NoMethodError:
undefined method `allow_value' for #<RSpec::ExampleGroups::Person::Age:0x007feb239fa6a8>
This is due to Rails 4.1 (specifically, Spring) revealing a weak point of shoulda-matchers

Show archive.org snapshot
.
Solution
The solution is to follow the gem's installation guide Show archive.org snapshot :
# Gemfile
gem 'shoulda-matchers', require: false
# spec/rails_helper.rb if present, spec/spec_helper.rb else
require 'rspec/rails'
require 'shoulda/matchers'
