使用 rr 生成块 [英] yield to a block using rr

问题描述

我正在尝试使用 rr 测试以下代码:

I'm trying to test the following code using rr:

response = RestClient.get(url, {:params => params}){|response, request, result| response }

在 vanilla rspec 中，你会做这样的事情:

In vanilla rspec, you would do something like this:

RestClient.should_receive(:get).with(url, {:params => params}).and_yield(response, request, result)

我将如何使用 rr 做同样的事情?

How would I do the same with rr?

设置:

let(:url) { "http://localhost/" }
let(:params) { {:item_id => 1234, :n => 5} }
let(:response) { Object.new }
let(:request) { Object.new }
let(:result) { Object.new }

我尝试了很多变体:

mock(RestClient).get(url, {:params => params}) { response, request, result }

和

mock(RestClient).get(url, {:params => params}, &proc/lambda{}).return(result)

和

mock(RestClient).get(url, {:params => params}).yields(response, request, result)

和

mock(RestClient).get(url, {:params => params}).returns do |proc_as_block|
  response
end

但它们都不起作用.

mock(RestClient).get(url, {:params => params}).yields(response, request, result) { response }
