Sudarsan Reddy 68d370af19 TUN-6617: Dont fallback to http2 if QUIC conn was successful. 
cloudflared falls back aggressively to HTTP/2 protocol if a connection
attempt with QUIC failed. This was done to ensure that machines with UDP
egress disabled did not stop clients from connecting to the cloudlfare
edge. This PR improves on that experience by having cloudflared remember
if a QUIC connection was successful which implies UDP egress works. In
this case, cloudflared does not fallback to HTTP/2 and keeps trying to
connect to the edge with QUIC.

README.md

Requirements

  1. Python 3.7 or later with packages in the given requirements.txt

    • E.g. with conda:
    • conda create -n component-tests python=3.7
    • conda activate component-tests
    • pip3 install -r requirements.txt

  2. Create a config yaml file, for example:

cloudflared_binary: "cloudflared"
tunnel: "3d539f97-cd3a-4d8e-c33b-65e9099c7a8d"
credentials_file: "/Users/tunnel/.cloudflared/3d539f97-cd3a-4d8e-c33b-65e9099c7a8d.json"
classic_hostname: "classic-tunnel-component-tests.example.com"
origincert: "/Users/tunnel/.cloudflared/cert.pem"
ingress:
- hostname: named-tunnel-component-tests.example.com
  service: hello_world
- service: http_status:404
  1. Route hostname to the tunnel. For the example config above, we can do that via
   cloudflared tunnel route dns 3d539f97-cd3a-4d8e-c33b-65e9099c7a8d named-tunnel-component-tests.example.com

  1. Turn on linter If you are using Visual Studio, follow https://code.visualstudio.com/docs/python/linting to turn on linter.

  2. Turn on formatter If you are using Visual Studio, follow https://code.visualstudio.com/docs/python/editing#_formatting to turn on formatter and https://marketplace.visualstudio.com/items?itemName=cbrevik.toggle-format-on-save to turn on format on save.

  3. If you have cloudflared running as a service on your machine, you can either stop the service or ignore the service tests via --ignore test_service.py

How to run

Specify path to config file via env var COMPONENT_TESTS_CONFIG. This is required.

All tests

Run pytest inside this(component-tests) folder

Specific files

Run pytest <file 1 name>.py <file 2 name>.py

Specific tests

Run pytest file.py -k <test 1 name> -k <test 2 name>

Live Logging

Running with -o log_cli=true outputs logging to CLI as the tests are. By default the log level is WARN. --log-cli-level control logging level. For example, to log at info level, run pytest -o log_cli=true --log-cli-level=INFO. See https://docs.pytest.org/en/latest/logging.html#live-logs for more documentation on logging.
