Ignore some requests?

[simon-weber]

Imagine this code:

# app code
def handle_request():
    requests.get('http://example.com')  # I want to record this

def test_app():
    # Imagine we're doing a live server test.
    # The app is running at localhost, and that handler is mounted at the root.
    with vcr.use_cassette('cassette.yaml'):
        server_response = requests.get('http://localhost/')  # but, this gets recorded too

I'm working around this right now by using pycurl - which VCR.py can't mock - when exercising the app endpoint.

Is there a better way of ignoring some requests? The patch for requests looks pretty deep, and I can't put the vcr context manager inside app code.

I'm trying to figure out what the API for this should look like. It's hard to disable the patch inside the app code without being able to modify the app code itself.

It's probably easiest not to actually disable the patch - you're right, that seems difficult - but to introduce a per-host filter in the stub. I'm not too familiar with the inner workings of httplib, but if every set of requests to a host is preceded by a call to connect, you could use it to set a per-stub flag to pass requests through.

Then we could expose something like with_cassette(ignore_hosts=['localhost', '127.0.0.1']).

The Ruby VCR lib has ignore some requests implemented. I am particularly interested in ignore_localhost option, however just making available an ignore_request call back or handler would be great as well.

mm nice, I like the Ruby VCR API.
