How to host the Kestrel server in a test?

问题

I need to test my ASP.NET Core routes and other configuration of my IWebHost, along with WebSocket code. For this I believe actually hosting Kestrel within my automated tests is the best approach.

How can I host configure the IWebHost such that it listens to an HttpMessageHandler that I have prepared instead of listening on an actual port so I can mock up messages handed to it? Or is there a better way?

I can't even find a property that discloses which port it listens to by default.
