Have test. I check helper_method :gta_data

if @dynamic_page
  gaPageUid = 'category-' + @dynamic_page.uid
elsif @product
  gaPageUid = 'product'
else
  gaPageUid = 'other'
end

describe '#gtm_data' do
  before :each do
    I18n.region = "de"
    I18n.language = "de"
    I18n.locale = "de"
  end

  context "when dynamic page" do
    let!(:object) {
      FactoryGirl.create(:dynamic_page_published,
                         og_title: translation_for(:de),
                         og_site_name: translation_for(:de),
                         og_description: translation_for(:de),
                         slug: "/with-og-attributes")
    }
    it do
      expect(subject.gtm_data).to eq({gaLocale: 'de', gaLanguage: 'de', gaRegion: 'de',
                                      gaPageUid: 'category-' + object.uid})
    end

  end
end

I get the following message.

   expected: {:gaLocale=>"de", :gaLanguage=>"de", :gaRegion=>"de", :gaPageUid=>"category-misc-1"}
   got: {:gaLocale=>nil, :gaLanguage=>nil, :gaRegion=>"de", :gaPageUid=>"other"}
