VCR.py has a few log messages you can turn on to help you figure out if HTTP requests are hitting a real server or not. You can turn them on like this:
import vcr import requests import logging logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from vcrpy vcr_log = logging.getLogger("vcr") vcr_log.setLevel(logging.INFO) with vcr.use_cassette('headers.yml'): requests.get('http://httpbin.org/headers')
The first time you run this, you will see:
INFO:vcr.stubs:<Request (GET) http://httpbin.org/headers> not in cassette, sending to real server
The second time, you will see:
INFO:vcr.stubs:Playing response for <Request (GET) http://httpbin.org/headers> from cassette
If you set the loglevel to DEBUG, you will also get information about which matchers didn’t match. This can help you with debugging custom matchers.
