Question

我开始认为它是ruby的版本我使用的是ruby-1.9.3-p125，或者可能是你的新版本很难分辨的宝石。我正在使用Rile第4版的Agile Web Development一书构建购物车应用程序。如果有人可以提供帮助，我将非常感谢，谢谢

我正在处理同样的错误数小时，希望这有帮助

您的test / unit / product_test.rb应如下所示

class PostTest < ActiveSupport::TestCase
    test "product attributes must not be empty" do
      product = Product.new
      assert product.invalid?
      assert product.errors[:title].any?
      assert product.errors[:description].any?
      assert product.errors[:price].any?
      assert product.errors[:image_url].any?
    end
end

当使用Rails 3.2进行rake测试时，如何确定错误是什么？
