include javascript rspec matcher

include_javascript.rb

RSpec::Matchers.define :include_javascript do |expected|

  match do |actual|
    actual && actual.match(/<script src="\/javascripts\/#{expected}\.js.+ type="text\/javascript"><\/script>/)
  end

  failure_message_for_should do |actual|
    "expected that javascript tag #{expected} would be present, but was not"
  end

  failure_message_for_should_not do |actual|
    "expected that javascript tag #{expected} would not be present, but was"
  end

  description do
    "include javascript tag #{expected}"
  end
end

Seems like it has a double quote requirement

Yes it does, but thats just the way it gets output from javascript_include_tag. No sense in supporting people who don't use the Rails helpers!
