Example websocket test with pytest and asyncio

Hi,

I'm looking for an example of a functional websocket test that will exercise both client and server in the same test. I'm having a hard time getting https://github.com/crossbario/autobahn-python/blob/master/autobahn/asyncio/test/test_aio_websocket.py to work ( I can see it's marked as skipped, but I still wanted to try to revive it).

Something as simple as the echo client/server example but within pytest would work very well - looking mostly to see how to wire-up the client-server integration with txaio and pytest-asyncio.

The context is that we have a large code-base that is heavily dependent on autobahn-python but existing tests require a running server, which is rather unorthodox, so we've launched a new project to isolate the tests but so far we've been hampered by test setup issues. Any help will be really appreciated.

Start with autobahn/asyncio/test/test_aio_websocket.py, which the issue identifies as a skipped websocket test, and compare it with the echo client/server example. Investigate how the test should connect the client and server through txaio, pytest, and pytest-asyncio; done means a functional same-test integration example that does not require an externally running server.
