用Javascript（Rspec，Spork和FactoryGirl启动）的水豚

Question

我有一个异步的JavaScript函数，我需要用水豚测试。我知道我必须在测试中使用js: true选项，并设置config.use_transactional_fixtures = false，然后输入一些database_cleaner，但我仍然无法正常工作。

cart_spec贯穿将项目添加到购物车并购买它的整个过程（因此它嵌套得相当深）。

checkout.html.erb使用stripe库来处理信用卡。这就是我需要测试的javascript功能。

当我使用js: true选项运行测试时，sports_url上不存在“添加到购物车”的测试失败，表明运动未保存到数据库。

当我运行没有js: true选项的测试时，除it "should warn user that cc number is invalid" do之外的所有测试都通过了，因为那是javascript所在的位置。

我正在运行spork并尝试重新启动服务器。

编辑

的问题是，我的测试运行在域名www.example.com，所以我sports_url被定向至www.example.com/sports。我问了一个新问题here。如果我用sports_path访问它，它的效果很好。

以下是文件：

cart_spec：

require "spec_helper" 

describe "Cart" do 
    before do 
    @user = FactoryGirl.create(:user) 
    @cart = @user.carts.create! 
    end 

    describe "using stripe" do 
     before do 
     @sport = FactoryGirl.create(:sport) 
     end 

     describe "user adds sport to cart", js: true do 
     before do 
      visit sports_url 
      click_link "Add to Cart" 
     end 

     it "should be checkout page" do 
      page.should have_content("Total") 
     end 

     describe "user clicks checkout" do 
      before do 
      click_button "Checkout" 
      end 

      it "should redirect user to sign in form" do 
      page.should have_selector('h2', text: "Sign in") 
      end 

      describe "user logs on" do 
      before do 
       fill_in "Email", with: @user.email 
       fill_in "Password", with: @user.password 
       click_button "Sign in" 

      end 

      it "should be on checkout page" do 
       page.should have_selector('h2', text: "Checkout") 
      end 

      describe "user fills in form" do 
       context "with invalid cc number" do 
       before do 
        fill_in "card-number", with: 42 
        click_button "Submit Payment" 
       end 

       it "should warn user that cc number is invalid" do 
        page.should have_content("Your card number is invalid") 
       end 
       end 
      end 

      end 
     end 
     end 
    end 

    describe "GET /carts/checkout" do 
    subject { @cart } 

    it { should respond_to(:paypal_url) } 
    it { should respond_to(:apply_discount) } 

    it "paypal_url contains notification" do 
     @cart.paypal_url(root_url, payment_notifications_url).should include("&notify_url=http%3A%2F%2Fwww.example.com%2Fpayment_notifications") 
    end 

    it "paypal_url contains invoice id" do 
     @cart.paypal_url(root_url, payment_notifications_url).should match /&invoice=\d+&/ 
    end 

    it "paypal_url contains return url" do 
     @cart.paypal_url(root_url, payment_notifications_url).should include("&return=http%3A%2F%2Fwww.example.com") 
    end 
    end 

    describe "GET /carts/discount" do 
    it "should apply discount to all line items" do 
     @cart.line_items.build(:unit_price => 48) 

     @cart.apply_discount 

     @cart.line_items.each do |lineItem| 
      lineItem.unit_price.should == 9.99 
     end 
    end 
    end 

end

Answer 1

问题是我在使用visit <route>_url。 rails测试的默认域名是exmaple.com，所以我的浏览器试图访问www.example.com/sports，这是由国际互联网命名委员会慷慨保留的。

我将这些改为visit <route>_path，事情很好。

Answer 2

很难给你确切的回答。

当您运行JS规格时，有2个进程。有可能，当你在并行访问页面时，记录不会被保存。

1. 尝试等待，直到@sport保存到数据库。 添加

wait_until { page.has_content? "Add to Cart" }

前

click_link "Add to Cart"

水豚将等待这些话（2秒以内）。要增加默认的等待时间，请将Capybara.default_wait_time = 5添加到spec_helper。

1. 确保DatabaseCleaner策略确实是:truncation。我看到你的spec_helper。只是检查两次:)
