rspec嘲讽对象属性赋值

Question

我有一个rspec模拟对象，值被赋值为属性。我很努力地在我的rspec测试中达到这个期望值。只是想知道sytax是什么？代码：

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 

测试

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 

问题是我收到此错误：

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") 

让我怎么设置对象的属性分配的期望呢？

感谢

Answer 1

Ruby中没有“属性赋值”这样的事情。在Ruby中，的一切都是是一个方法调用。所以，你嘲笑setter方法，就像对其他任何方法：

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

BTW：这些测试打印出的诊断消息不只是shpw。在这种情况下，消息已经告诉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，你发布已经告诉你什么是方法的名称是你需要模拟消息在那里：

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

找到关于它的here

链接这是通过简单地添加：creationDate =而并非只是：creationDate的期望。
