Problem running fuzzingserver in virtualenv

I tried both Python2 and PyPy with no luck in testing my server. I follow the docs, but wstest fails in unhandled exception:

That’s ok, totally understand.😃 Anyways, I’m grateful for the great yet not perfect test suite!😃 Thank you!

I guess you are actually right. I just gave it another try, and:

4.2.1. Reading the Client’s Opening Handshake … 3. An |Upgrade| header field containing the value “websocket”, treated as an ASCII case-insensitive value. 4. A |Connection| header field that includes the token “Upgrade”, treated as an ASCII case-insensitive value.

My bad.
