我的单元测试：

     require 'test_helper'

class ProductTest < ActiveSupport::TestCase

  def new_product
      product = Product.new(:title => "MyBook",
                          :description => "Famouse myBook",
                          :image_url => "zz.jpg")

  end

  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

   test "product must be postive price" do
        product = Product.new(:title => "MyBook",
                          :description => "Famouse myBook",
                          :image_url => "zz.jpg")

        product.price = -1
        assert product.invalid?
        assert_equal "must be greater than or equal to 0.01",
        product.errors[:price].join('; ')

        product.price = 0
        assert product.invalid?
        assert_equal "must be greater than or equal to 0.01",
        product.errors[:price].join('; ')

        product.price = 1
        assert product.valid?
  end 


  test "image url" do
       ok = %w{fred.gif fred.jpg fred.png FRED.JPG FRED.PNG FRED.GIF
                     http://a.b.c/x/y/z/fred.gif}
            bad = %w{fred.doc fred.gif/more fred.gif.more}    

            ok.each do |name|
              assert new_product(name).valid?, "#{name} shoudn't be invalid"
            end


            bad.each do |b|
             assert new_product(name).invalid?, "#{name} shoudn't be valid"
            end
       end

编辑：祝贺谢谢你帮我弄清楚什么是错的

require 'test_helper'

                          :description => "Famouse myBook",
                          :price => 1 ,
                          :image_url => image_url)

  end

  test "product attributes must not be empty" do
