Question

我正在关注敏捷网站开发。我正处于本书的单元测试阶段。我跟着它发球了。但是当我运行rake时，我遇到以下错误：测试单位

我的test / models / product_test.rb如下所示：

require 'test_helper'

 class ProductTest < ActiveSupport::TestCase
    fixtures :products
   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

 test "product price must be positive" do
     product = Product.new(title:        "My Book Title",
                      description:  "yyy",
                      image_url:    "zzz.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

  def new_product(image_url)
    Product.new(title:       "My Book Title",
                description: "yyy",
                price:       1,
                image_url:   image_url)
  end

  test "image url" do
    ok = %w{ fred.gif fred.jpg fred.png FRED.JPG FRED.Jpg
             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} shouldn't be invalid"
    end

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

  test "product is not valid without a unique title" do
    product = Product.new(title:        products(:ruby).title,
                          description:  "yyy", 
                          price:        1, 
                          image_url:    "fred.gif")

    assert !product.save
    assert_equal "has already been taken", product.errors[:title].join('; ')
  end

  test "product is not valid without a unique title - i18n" do
    product = Product.new( title:        products(:ruby).title,
                       description:  "yyy", 
                       price:        1, 
                       image_url:    "fred.gif")

    assert !product.save
    assert_equal I18n.translate('activerecord.errors.messages.taken'),
                 product.errors[:title].join('; ')
  end

我的test / fixtures / products.yml看起来像这样

# Read about fixtures at http://api.rubyonrails.org/classes/ActiveRecord/FixtureSet.html

one:
  title: MyString
  description: MyText
  image_url: MyString
  price: 9.99

two:
  title: MyString
  description: MyText
  image_url: MyString
  price: 9.99

ruby:
    title: Programming Ruby 1.9 
    description:
        Ruby is the fastest growing and most exciting dynamic
        language out there.  If you need to get working programs
        delivered fast, you should add Ruby to your toolbox.

我真的很擅长朝着正确的方向点头，或者建议会非常感激。感谢

修改

继承我的app / models / product.rb

class Product < ActiveRecord::Base
    validates :title, :description, :image_url, presence: true
    validates :price, numericality: {greater_than_or_equal_to: 0.01}
    validates :title, uniqueness: true

    validates :image_url, allow_blank: true, format: { 
      with: %r{\.(gif|jpg|png)\Z}i,
      message: 'must be a URL for GIF, JPG or PNG image.'
      }
end

Answer 1

测试文件 - test/models/product_test.rb - 语法错误;这就是导致错误信息。第12行和第12行有两个end语句。该文件中的13个。删除其中一个并将其放在文件的末尾;这将解决这个问题。

由于第12行的额外end，测试文件在该点被认为是完整的，并且下一行在不同的上下文中被解释导致问题。

遵循敏捷Web开发，但我得到错误
