我想學習TDD,這是我作業的一部分,我無法弄清楚如何去做。Rspec創建控制器操作的測試有什麼問題?
我想測試create
控制器動作,這裏是我的測試代碼:
require 'spec_helper'
describe MoviesController do
describe 'create' do
it 'should call the model method perform create!' do
Movie.should_receive(:create!).with({"title" => 'Milk', "rating" => 'R'})
post :create, :movie => {:title => 'Milk', :rating => 'R'}
end
end
end
但我得到:
Failures:
1) MoviesController create should call the model method performe create!
Failure/Error: post :create, :movie => {:title => 'Milk', :rating => 'R'}
NoMethodError:
undefined method `title' for nil:NilClass
# ./app/controllers/movies_controller.rb:50:in `create'
# ./spec/controllers/movies_controller_spec.rb:7:in `block (3 levels) in <top (required)>'
Finished in 0.21714 seconds
這裏是創建行動,我對測試。是的,這是TDD,是的,我測試 工作代碼,並且它的測試不工作:d
def create
@movie = Movie.create!(params[:movie])
flash[:notice] = "#{@movie.title} was successfully created."
redirect_to movies_path
end
我甚至不知道爲什麼我得到了未定義的方法錯誤訊息?我還有其他幾個測試通過了,但爲了簡單起見,我在這段代碼片段中刪除了,所以我不認爲它與db/model相關的配置問題有關。但爲什麼它不工作,以及如何改變它?
乾杯
Should_receive將返回零,即使它沒有收到的匹配參數「{」標題「=>‘牛奶’,‘等級’=>‘R’}」,所以我需要趕上返回值,我知道了嗎? – 2012-03-31 03:22:20
對不起,我現在明白了,它來自控制器線。謝謝@ctide,拯救了我的一天! – 2012-03-31 03:28:53
