     This is meant to be used as 'body' argument of the requests_mock.get()
     method.
 
     It will look for files on the local filesystem based on the requested URL,
     using the following rules:
 
     - files are searched in the DATADIR/<hostname> directory
 
     - the local file name is the path part of the URL with path hierarchy
       markers (aka '/') replaced by '_'
 
     Eg. if you use the requests_mock fixture in your test file as:
 
         requests_mock.get('https://nowhere.com', body=get_response_cb)
         # or even
         requests_mock.get(re.compile('https://'), body=get_response_cb)
 
     then a call requests.get like:
 
         requests.get('https://nowhere.com/path/to/resource')
 
     will look the content of the response in:
 
         DATADIR/resources/nowhere.com/path_to_resource
 
     Args:
         request (requests.Request): Object requests
         context (requests.Context): Object holding response metadata
                                     information (status_code, headers, etc...)
         ignore_urls (List): urls whose status response should be 404 even if
                             the local file exists
+        visit (Optional[int]): Visit number for the given url (can be None)
