Rspec3:向控制器发送异常
Rspec3:向控制器发送异常
提问于 2014-07-10 12:48:44
我想测试我的控制器，并确保它在接收到ActiveRecord::RecordNotFound时呈现适当的模板。
控制员：
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我的测试：
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我对我的测试一点也不确定，这会引发一个错误：NoMethodError: undefined method 'each' for #<String:0xbcdf388>
如何正确地写我的考试？

我成功地用以下代码模拟了一个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)
