vcr.net's Issues

Setting RecordMode to 'None' for a Request with no Recorded Cassette Results in MatchNotFoundException

Hello,
I was looking for a means to disable VCR.NET recording/playback (while sussing out the external resource / etc., without having to go and delete the newly-created Cassette file after every test run). So, I attempted the following:

_vcr.UseCassette(cassetteName, RecordMode.None)

• Expected behavior: The HTTP request goes through, with VCR.NET effectively no-oping. No recording, no playback attempts.
• Actual behavior: MatchNotFoundException is thrown (if there's no cassette file recorded)

Is there some other way I can inform VCR to basically do nothing for playback and recording so I can just let the HTTP traffic flow through without any VCR interaction?

DefaultRequestMatcher IgnoreHeaders not working

In my test case, I'm trying to use the RecordMode.Once to record the cassettes in the first run and then replay the payloads during consecutive runs. The API that I'm recording is using API key authentication in headers. I don't want to store the API Key in a cassette in source control and I don't want to compare this header during playbacks.

I tried to use the IgnoreHeaders property of DefaultRequestMatcher but it is not used during the recording (which conceptually makes sense for your design). On the other hand, when replaying, the IgnoreHeaders seems to be used as a blacklist, but it should be a whitelist for comparison.

if (IgnoreHeaders.Contains(recordedHeader.Key))
    return false; // <---

should be:

if (IgnoreHeaders.Contains(recordedHeader.Key))
    continue; // <---

1. Is my thinking correct?
2. Is there a way to ignore a header when recording cassettes?
