Rspec3：發送異常控制器

我想測試我的控制器，並確保每當收到一個ActiveRecord::RecordNotFoundRspec3：發送異常控制器

控制器它呈現了正確的模板：

class QuestionnaireController < ApplicationController 

    rescue_from ActiveRecord::RecordNotFound, with: :verses_not_found 

    def poem 
    @questionnaire = JSON.parse(session[:questionnaire], symbolize_names: true) 
    rawVerses = VerseSelector.select_verses(@questionnaire[:trait_category], @questionnaire[:message_category]) 
    @poem = PoemCustomizer.customize_poem(rawVerses, @questionnaire) 
    end 

    def verses_not_found 
    render 'questionnaire/verses_not_found' 
    end 
end

我的測試：

describe "GET 'poem'" do 
    it "renders questionnaire/verses_not_found.html if theres an ActiveRecord::RecordNotFound exception" do 
    verse_selector = double("VerseSelector", select_verses: ActiveRecord::RecordNotFound.new("Verses not found")) 
    get 'poem', nil, {questionnaire: {receiver_name:"a",location:"b",relationship:"coach",trait_category:"adventurous venturous",message_category:"You hurt my feelings"}}.to_json 
    expect(response).to render_template(:verses_not_found) 
    end 
end

我不確定我的測試，它目前會產生一個錯誤：NoMethodError: undefined method 'each' for #<String:0xbcdf388>

如何正確編寫我的測試？

我存根詩提高RecordNotFound，然後進行測試，看是否調用詩自己，當收到verses_not_found。然後再進行一次測試，看看後一種方法是否能夠提供正確的頁面 –

我會創建一個匿名動作，引發RecordNotFound並獲取該動作來驗證預期的模板是否呈現 – Benj

我設法用下面的代碼來模擬ActiveRecord::RecordNotFound：

it "renders questionnaire/verses_not_found.html if theres an ActiveRecord::RecordNotFound exception" do 
    verse_selector = double("verse_selector") 
    allow(verse_selector).to receive(:select_verses).and_return(ActiveRecord::RecordNotFound.new()) 
    get 'poem', nil, {"questionnaire" => {"receiver_name"=> "a","location"=> "b","relationship"=> "coach","trait_category"=> "adventurous venturous","message_category"=> "You hurt my feelings"}.to_json} 
    expect(response).to render_template(:verses_not_found) 
end
