rspec嘲諷對象屬性賦值

Question

我有一個rspec模擬對象，值被賦值爲屬性。我很努力地在我的rspec測試中達到這個期望值。只是想知道sytax是什麼？代碼：

def create 
@new_campaign = AdCampaign.new(params[:new_campaign]) 
@new_campaign.creationDate = "#{Time.now.year}/#{Time.now.mon}/#{Time.now.day}" 
if @new_campaign.save 
    flash[:status] = "Success" 
else 
    flash[:status] = "Failed" 
end end 

測試

it "should able to create new campaign when form is submitted" do 
    campaign_model = mock_model(AdCampaign) 
    AdCampaign.should_receive(:new).with(params[:new_campaign]).and_return(campaign_model) 
    campaign_model.should_receive(:creationDate).with("#{Time.now.year}/#{Time.now.mon}/#{Time.now.day}")campaign_model.should_receive(:save).and_return(true) 
    post :create 

    flash[:status].should == 'Success' 
    response.should render_template('create') end 

問題是我收到此錯誤：

Spec::Mocks::MockExpectationError in 'CampaignController new campaigns should able to create new campaign when form is submitted' Mock "AdCampaign_1002" received unexpected message :creationDate= with ("2010/5/7") 

讓我怎麼設置對象的屬性分配的期望呢？

感謝

Answer 1

Ruby中沒有「屬性賦值」這樣的事情。在Ruby中，的一切都是是一個方法調用。所以，你嘲笑setter方法，就像對其他任何方法：

campaign_model.should_receive(:creationDate=).with(...) 

BTW：這些測試打印出的診斷消息不只是shpw。在這種情況下，消息已經告訴你你需要知道的一切：

Spec::Mocks::MockExpectationError in 'CampaignController new campaigns should able to create new campaign when form is submitted' Mock "AdCampaign_1002" received unexpected message :creationDate= with ("2010/5/7")

正如你所看到的，你發佈已經告訴你什麼是方法的名稱是你需要模擬消息在那裏：

unexpected message :creationDate= with ("2010/5/7") 
        ^^^^^^^^^^^^^^

鏈接這是通過簡單地添加：creationDate =而並非只是：creationDate的期望。
