Hi,
I am trying to add webhook support to the otherwise command-line
application using Waitress web server. Webhook endpoints are defined as
Pyramid routes. I also wish to test this functionality using pytest.
The server gets created fine, but on pytest shutdown, I am getting an
error: OSError: [Errno 9] Bad file descriptor. What would be the nice way
to spin Waitress up and down on demand?
How do I create the server instance:
def create_webhook_server(host: str, port: int, username: str, password:
str, queue: Queue) -> MultiSocketServer:
app = create_pyramid_app(username, password, queue, production=False)
server = create_server(app, host=host, port=port)
logger.info("Webhook server will spawn at %s:%d", host, port)
return server
How do I start and test the server in the unit test:
def test_auth_ok():
"""Username and password allow to access the webhook"""
queue = Queue()
server = create_webhook_server("127.0.0.1", 5000, "test", "test", queue)
server_url = "http://test:test@127.0.0.1:5000";
webhook_thread = Thread(target=server.run)
webhook_thread.start()
# Test home view
resp = requests.get(server_url)
assert resp.status_code == 200
server.close()
The exception I am getting:
