Ruby on Rails - TDD 测试时出现测试错误
Ruby on Rails - TDD Testing errors while testing
我要回去努力学习TDD测试了。我正在编写一个教程，该教程希望我创建将与主题相关联的 SponsoredPosts。
我对 TDD 测试还比较陌生，所以遇到了一些小问题。
我还没有创建一个由两个词组成的控制器或模型 "Sponsored" "Posts" 所以我不确定处理它们时的协议，所以我将为你提供与我认为相关的一切然后希望你能告诉我我哪里出错了。我相信我只是混淆了模型和控制器的名称，因为正如您在我的模式文件中看到的那样，"sponsored_posts" 的 table 有一个 "topic_id" 属性.我承认，就知道如何处理它们而言，我不是最擅长命名模型或控制器的，因此您还可以提供任何解释以进一步帮助我理解我在命名它们时出错的地方 非常有帮助.
这是我的 Sponsored_Posts_Controller_Spec:
require 'rails_helper'
include RandomData
RSpec.describe SponsoredPostsController, type: :controller do
let (:my_topic) { Topic.create!(name: RandomData.random_sentence, description: RandomData.random_paragraph) }
let (:my_sponsored_post) { my_topic.sponsored_posts.create!(title: RandomData.random_sentence, body: RandomData.random_paragraph, price: 6) }
describe "GET show" do
it "returns http success" do
get :show, topic_id: my_topic.id, id: my_sponsored_post.id
expect(response).to have_http_status(:success)
end
it "renders the #show view" do
get :show, topic_id: my_topic.id, id: my_sponsored_post.id
expect(response).to render_template :show
end
it "assigns my_sponsored_post to @sponsored_post" do
get :show, topic_id: my_topic.id, id: my_sponsored_post.id
expect(assigns(:sponsored_posts)).to eq(my_sponsored_post)
end
end
end
这是我的 Sponsored_Post 型号规格：
require 'rails_helper'
include RandomData
RSpec.describe SponsoredPost, type: :model do
let(:topic) { Topic.create!(name: RandomData.random_sentence, description: RandomData.random_paragraph) }
let(:sponsored_post) { topic.sponsored_posts.create!(title: RandomData.random_sentence, body: RandomData.random_paragraph, price: 6) }
it { should belong_to(:topic) }
describe "attributes" do
it "should respond to title" do
expect(sponsored_posts).to respond_to(:title)
end
it "should respond to body" do
expect(sponsored_posts).to respond_to(:body)
end
it "should respond to price" do
expect(sponsored_posts).to respond_to(:price)
end
end
end
这是我的 SponsoredPosts 控制器：
class SponsoredPostsController < ApplicationController
def show
@sponsored_post = Sponsored_post.find(params[:id])
end
def new
end
def edit
end
end
这是我的 SponsoredPost 模型：
class SponsoredPost < ActiveRecord::Base
belongs_to :topic
end
这是我的架构文件：
ActiveRecord::Schema.define(version: 20151102190350) do
create_table "advertisements", force: :cascade do |t|
t.string "title"
t.text "copy"
t.integer "price"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "comments", force: :cascade do |t|
t.text "body"
t.integer "post_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
add_index "comments", ["post_id"], name: "index_comments_on_post_id"
create_table "posts", force: :cascade do |t|
t.string "title"
t.text "body"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "topic_id"
end
add_index "posts", ["topic_id"], name: "index_posts_on_topic_id"
create_table "questions", force: :cascade do |t|
t.string "title"
t.text "body"
t.boolean "resolved"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "sponsored_posts", force: :cascade do |t|
t.string "title"
t.text "body"
t.integer "price"
t.integer "topic_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
add_index "sponsored_posts", ["topic_id"], name: "index_sponsored_posts_on_topic_id"
create_table "topics", force: :cascade do |t|
t.string "name"
t.boolean "public", default: true
t.text "description"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
end
这是我 运行 SponsoredPost 控制器的规范时的输出：
1) SponsoredPostsController GET show returns http success
Failure/Error: let (:my_sponsored_post) { my_topic.sponsored_posts.create!(title: RandomData.random_sentence, body: RandomData.random_paragraph, price: 6) }
ActiveRecord::UnknownAttributeError:
unknown attribute 'topic_id' for SponsoredPost.
2) SponsoredPostsController GET show renders the #show view
Failure/Error: let (:my_sponsored_post) { my_topic.sponsored_posts.create!(title: RandomData.random_sentence, body: RandomData.random_paragraph, price: 6) }
ActiveRecord::UnknownAttributeError:
unknown attribute 'topic_id' for SponsoredPost.
3) SponsoredPostsController GET show assigns my_sponsored_post to @sponsored_post
Failure/Error: let (:my_sponsored_post) { my_topic.sponsored_posts.create!(title: RandomData.random_sentence, body: RandomData.random_paragraph, price: 6) }
ActiveRecord::UnknownAttributeError:
unknown attribute 'topic_id' for SponsoredPost.
这是我 运行 模型规格时的输出：
1) SponsoredPost should belong to topic
Failure/Error: it { should belong_to(:topic) }
Expected SponsoredPost to have a belongs_to association called topic (SponsoredPost does not have a topic_id foreign key.)
# ./spec/models/sponsored_post_spec.rb:9:in `block (2 levels) in <top (required)>'
2) SponsoredPost attributes should respond to title
Failure/Error: expect(sponsored_posts).to respond_to(:title)
NameError:

这里有什么我可以给你的建议：
- 你的控制器里面有错字应该是
SponsoredPost 而不是 Sponsored_post
在您的控制器测试中，未定义变量 sponsored_posts，可能是：
SponsoredPost.create!(标题:RandomData.random_sentence,body:RandomData.random_paragraph,价格:6,主题:my_topic)
你的模型测试好像也是一样的问题
