Ruby on rails 命名错误：以Rspec为单位

我目前正在两个文件上进行rspec测试，我得到了这些关于未定义方法的失败。我需要更多关于如何准确修复这些错误的钙化，谢谢

失败：

  1) FavoritesController#create creates a favorite for the current user and specified post
     Failure/Error: @post = create(:post)
     NoMethodError:

这是投票_controller _spec.rb文件：

require 'rails_helper'

describe FavoritesController do

  include Devise::TestHelpers

  before do 
    @post = create(:post)
    @user = create(:user)
    sign_in @user
  end

  describe '#create' do
    it "creates a favorite for the current user and specified post" do
      expect( @user.favorites.find_by(post_id: @post.id) ).to be_nil

      post :create, { post_id: @post.id }

      expect( @user.favorites.find_by(post_id: @post.id) ).not_to be_nil
    end
  end

  describe '#destroy' do
    it "destroys the favorite for the current user and post" do
      favorite = @user.favorites.where(post: @post).create
      expect( @user.favorites.find_by(post_id: @post.id) ).not_to be_nil

      delete :destroy, { post_id: @post.id, id: favorite.id }

      expect( @user.favorites.find_by(post_id: @post.id) ).to be_nil
    end
  end
end

require 'rails_helper'

 describe VotesController do

   include TestFactories

   describe '#up_vote' do
     it "adds an up-vote to the post" do
        request.env["HTTP_REFERER"] = '/'
       @user = authenticated_user
       @post = associated_post
       sign_in @user

       expect {
         post( :up_vote, post_id: @post.id )
       }.to change{ @post.up_votes }.by 1
     end
   end
 end

检查您是否有

config.include FactoryGirl:：Syntax:：Methods

内部

rails\u helper.rb

如果您在

rails\u helper.rb

文件中有上述行，则始终可以使用

FactoryGirl.create:user

您可能没有将

include designe:：TestHelpers

包含在

VotesController

的规范中，这就是为什么它在

方法中没有看到
签名的原因

你弄明白了吗？我得到了相同的错误，但只有当我显式运行有问题的文件时——运行所有规范不会引发此错误
