使用Rails Book進行敏捷Web開發會導致產品測試失敗

Question

運行測試時出現此錯誤消息，在瀏覽器中測試時，相關功能正常工作。

Error:
ProductsControllerTest#test_should_create_product:
StandardError: No fixture named 'three' found for fixture set 
'products'
    test/controllers/products_controller_test.rb:5:in `block in 
<class:ProductsControllerTest>'


bin/rails test test/controllers/products_controller_test.rb:24

Error:
ProductsControllerTest#test_should_get_index:
StandardError: No fixture named 'three' found for fixture set 
'products'
test/controllers/products_controller_test.rb:5:in `block in 
<class:ProductsControllerTest>'


bin/rails test test/controllers/products_controller_test.rb:14

這是我仔細檢查過的測試。

require 'test_helper'

class ProductsControllerTest < ActionDispatch::IntegrationTest
  setup do
    @product = products(:three)
    @update = {
        tite:         'lorxem Ipsum',
        description:  'Wibbles are fun!',
        image_url:    'lorem.jpg',
        price:        19.95
    }
  end

  test "should get index" do  
    get products_url
    assert_response :success
  end

 test "should get new" do
    get new_product_url
    assert_response :success
 end

  test "should create product" do
   assert_difference('Product.count') do
   post products_url, params: { product: @update }
  end

  assert_redirected_to product_url(Product.last)
end

  test "should show product" do
    get product_url(@product)
    assert_response :success
  end

  test "should get edit" do
    get edit_product_url(@product)
    assert_response :success
  end

  test "should update product" do
    patch product_url(@product), params: { product: @update }
    assert_redirected_to product_url(@product)
  end

  test "should destroy product" do
    assert_difference('Product.count', -1) do
      delete product_url(@product)
   end

    assert_redirected_to products_url
  end

結束

這是我的固定裝置

one:
  title: MyString
  description: MyText
  image_url: test.jpg
  price: 9.99

two:
  title: MyString
  description: MyText
  image_url: test.jpg
  price: 9.99

這是我在瀏覽器中可用的添加產品控制器代碼：

def create
    @product = Product.new(product_params)

    respond_to do |format|
      if @product.save
        format.html { redirect_to @product, notice: 'Product was 
successfully created.' }
        format.json { render :show, status: :created, location: 
@product }
      else
        format.html { render :new }
        format.json { render json: @product.errors, status: 
:unprocessable_entity }
      end
    end
  end

這是我的更新產品控制器代碼，可再次在瀏覽器中使用：

def update
    respond_to do |format|
      if @product.update(product_params)
        format.html { redirect_to @product, notice: 'Product was 
successfully updated.' }
        format.json { render :show, status: :ok, location: @product }
      else
        format.html { render :edit }
        format.json { render json: @product.errors, status: 
:unprocessable_entity }
      end
    end
  end

任何幫助或指導表示贊賞。

編輯：

這是測試日志：

現在，一項測試通過-更新一項-固定裝置中的產品具有相同的標題，並且標題驗證為唯一，從而失敗。

創建產品測試的任何幫助都將非常有用。

謝謝

Answer 1

您引用的產品夾具文件中沒有產品夾具。 @product = products(:three)期望在products.yml文件中找到一個名為：three的燈具，但是您只有：one和：two。 要么創建一個新產品三個夾具，要么將更改products(:three)更改為products(:one)或products(:two) 。

Answer 2

設法工作了這一點，這個問題是： tite: 'lorxem Ipsum',應該是title: 'lorxem Ipsum',

缺少的“ l”！
