find方法收到两次，而预期一旦

而写一些规格find方法收到两次，而预期一旦

QuestionsController GET #edit finds question to edit 
    Failure/Error: Question.should_receive(:find).with("#{question.id}").and_return(question) 
    (<Question(id: integer, title: string, body: text, created_at: datetime, updated_at: datetime, user_id: integer, up_votes: integer, down_votes: integer) (class)>).find("9") 
     expected: 1 time 
     received: 2 times 

class QuestionsController < ApplicationController 
    def edit 
    @question = Question.find(params[:id]) 
    end 
end

规格/控制器/ questions_spec.rb

describe QuestionsController do 
    describe 'get edit' do 
     it 'finds question to edit' do 
     question = create(:question) 
     user = create(:user) 
     sign_in user 
     Question.should_receive(:find).and_return question 
     get :edit, :id => question.id 
     end 
     it 'renders edit template' do 
     question = create(:question) 
     user = create(:user) 
     sign_in user 
     Question.stub(:find).and_return question 
     get :edit, :id => question.id 
     expect(responce).to render_template 'edit' 
     end 
    end 
    end

我需要Rspec，工厂女孩，database_cleaner我遇到了一个错误， Postgres

spec_helper中的database_cleaner配置

config.before(:suite) do 
    DatabaseCleaner.clean_with :truncation 
    DatabaseCleaner.strategy = :transaction 
    end 

    config.before(:each) do |group| 
    # The strategy needs to be set before we call DatabaseCleaner.start 
    DatabaseCleaner.strategy = :transaction 
    DatabaseCleaner.start 
    end 

    config.after(:each) do 
    DatabaseCleaner.clean 
    end 
    config.use_transactional_fixtures = false

我正在测试编辑操作。我在Question上设置期望值以在第一个示例中接收find，在第二个示例中找到stub find方法调用。我在第一个例子中遇到错误我认为这两个例子并不完全相互隔离。

错误消息似乎并不符合规范。首先，错误消息以'GET #edit'开始，而规范以'get edit'开始。其次，错误报告中的期望有一个“with”条款，而规范没有。 –

你应该做一个PUT请求：

put :edit, id: question.id
