# This includes a backported version of the Capybara string matchers David Chelimsky
# is preparing in https://github.com/dchelimsky/capybara/tree/rspec-matchers
#
# Looks like the string matchers will be included in Capybara 0.4.2 if the feature is ready.
#
# The branch have not being merged into master because it's missing support for the capybara
# page object.
#
# When we test a rendered cell with the `render_cell` method we get an ActionView::OutputBuffer
# instance, it is in short, a safe version of String, so we are testing a String, not a capybara
# page object. So the matchers are OK and the missing features won't bother us.
#
# Follow up in http://groups.google.com/group/ruby-capybara/browse_thread/thread/c8adaa8f750b1020
