fix for minitest-capybara when used with capybara 2.0.3
Raw
minitest-capybara fix
# put this in your test_helper.rb if you encounter the following error:
# NoMethodError: undefined method `failure_message' for Capybara::Helpers:Module
# (eval):19:in `block in assert_link'
# when using minitest-capybara with capybara 2.0.3 e.g. if you are stuck on Ruby 1.9.2
# and you will have decent error messages again
# (stolen from Capybara 2.1.0 on which minitest-capybara implicitely depends)
