RSpec 3-不建议使用“应该”

Question

如果不建议使用should，我不想启用它的用法。为此，新的expect语法是什么？

   describe '#show response' do 
        it "should return html data only" do 
          get :show, params: {:id => "bike"}
          response.header['Content-Type'].should include 'text/html'
        end

        it "should not return json data" do 
          get :show, params: {:id => "bike"}
          response.header['Content-Type'].should_not include 'application/json'
        end

        it "should not return js data" do 
          get :show, params: {:id => "bike"}
          response.header['Content-Type'].should_not include 'text/javascript'
        end
      end
    end

弃用警告：

使用rspec-expectations的旧should语法中的:should，但不显式启用语法已弃用。使用新的:expect语法或使用:should显式启用

config.expect_with(:rspec)
  { |c| c.syntax = :should }

。

您可能考虑使用expect().to eq()，因此在您的情况下：

expect(response.header['Content-Type'].include?('text/html')).to be true
expect(response.header['Content-Type'].include?('application/json')).to be false
expect(response.header['Content-Type'].include?('text/javascript')).to be false
