ruby-on-rails - 在 rails 中使用 rspec 模拟/ stub Controller recaptcha 方法

Question

我刚刚学习如何使用 stub 和模拟，我想模拟下面的 verify_recaptcha 方法来测试条件的两种结果。

我的 Controller 代码(DogMailsController)

      if verify_recaptcha(:model=>@email,:message=>"Verification code is wrong", :attribute=>"verification code")  
        if DogMail.make_mail dog_mail_params
          result = "success"
        else
          result = "fail"
        end
      else
        flash.delete(:recaptcha_error)
        flash.now[:error] = "Validation Failed. Please enter validation numbers/letters correctly at bottom."
        render :action => 'new', :locals => { :@email => DogMail.new(dog_mail_params)}
      end
     end

到目前为止我的规范

context "when master not signed in" do 
  context "when recaptcha verified" do 
    context "with valid params" do 
      it "should save the new dog mail in the database" do  

        expect{
          post :create, dog_mail: attributes_for(:dog_mail)
        }.to change(DogMail, :count).by(1)
      end
    end 
    context "with invalid params" do 
    end
  end

为了对 verify_recaptcha stub /模拟，我应该在 expect 上面放什么？我尝试了 DogMailsController.stub(:verify_recaptcha).and_return(false) 但它似乎不起作用。

您只需要 stub controller.verify_recaptcha，因此使用 RSpec 3 语法:

allow(controller).to receive(:verify_recaptcha).and_return(true)
