如何在测试方法中存根 HTTParty 请求？

Question

我创建了一个发出 HTTParty get 请求的函数。它引发了我需要测试的自定义错误消息。我尝试在测试中使用 Webmock 存根请求，但它引发了 <Net::OpenTimeout>。如果 url 是动态构造的，我如何存根获取请求？

def function(a , b)
# some logic , dynamic url constructed
response = HTTParty.get(url, headers: {"Content-Type" => 
 "application/json"})
if response.code != 200
  raise CustomError.new <<~EOF
    Error while fetching job details.
    Response code: #{response.code}
    Response body: #{response.body}
  EOF
end
JSON.parse(response.body)

考试

def test_function
WebMock.stub_request(:get, url).with(:headers => {'Content- 
  Type'=>'application/json'}).to_return(:status => 500)
# HTTParty.stub(get: fake_response)
err = assert_raises CustumError do
   c.function(a , b)
end

WebMock 允许您使用 "wildcard matching" 这样您就可以 stub requests matching a regular expression:

WebMock.stub_request(:get, /example/).to_return(status: 500)
