What is the best practical way of testing a multilingual application in rails?

Question

Suppose that I have a rails app that has 4 languages those german, english, french and swedish. I want to test this app with rspec for all locales. At the moment I test it like below.

I18n.available_locales = [:en, :de, :fr,:sv]


describe "Example Pages" do   

  subject { page }

  I18n.available_locales.each do |locale|

    describe "example page" do
      let(:example_text) { t('example.translation') }

      before { visit example_path(locale) }

      it { should have_selector('h1', text: example_text) }
      ...
    end
    ...   
  end
end

But to test the app for all locale I have to loop avalaible locales for every spec and this is a very painful process. I am looking for a very simple way to test for multilingual without injecting a locale loop for every spec. How can do that?
