如何在 Rspec 中存根载波? [英] How to stub carrierwave in Rspec?
问题描述
我想存根carrierwave 以防止它在我的测试期间获取网络上的图像.我将如何存根以实现这一目标?
I want to stub carrierwave to prevent it from fetch images on the web during my tests. How would I stub things to achieve this?
我的爬虫解析远程网页,并将一个图片网址保存到模型中.Carrierwave 将在保存操作期间自动获取该图像.它运作良好.
My crawler parses a remote web page, and saves one image url into the model. Carrierwave will fetch that image automatically during the save operation. It works well.
但是我有一个关于页面解析的测试,每次都会下载文件,导致测试速度变慢.
However I have a test about the parsing of pages, and every-time it will download the file, which slows down the testing.
更新:
我按如下方式安装上传器(在预先存在的回形针列中)
I mount the uploader as the following (in the pre-existing paperclip column)
mount_uploader :image, TopicImageUploader, :mount_on => :image_file_name
我试图存根以下内容,但都没有奏效:
I tried to stub the following, but neither worked:
Topic.any_instance.stub(:store_image!)
Topic.any_instance.stub(:store_image_file_name!)
Topic.any_instance.stub(:store_image_remote_url!)
推荐答案
TopicImageUploader.any_instance.stub(:download!)
