How to test render_to_response in Pyramid Python

Question

I have a piece of code that calls Pyramid's render_to_response. I am not quite sure how to test that piece. In my test, the request object that is sent in is a DummyRequest by Pyramid. How can I capture to_be_rendered.

from pyramid.renderers import render_to_response

def custom_adapter(response):
    data = {
        'message': response.message
    }

    to_be_rendered = render_to_response(response.renderer, data)

    to_be_rendered.status_int = response.status_code
    return to_be_rendered

Answer 1

I believe render_to_response should return a response object. You should be able to call custom_adapter directly in your unit test, providing a DummyRequest and make assertions on the Response object returned by your custom_adapter

def test_custom_adapter(self):
   dummy = DummyRequest() # not sure of the object here
   response = custom_adapter(dummy)
   self.assertEqual(response.status, 200)
