How to stub a HTTParty request inside a method for testing?

I have created a function that makes a HTTParty get request. It raises a custom error message that i need to test. I tried to stub the request using Webmock in the test but it is raising a <Net::OpenTimeout>. How can i stub the get request if the url is dynamically constructed?

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)

for the test

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
Solution

  • WebMock allows you to use "wildcard matching" so you can stub requests matching a regular expression:

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