Testing my Oak `Application` end-to-end

I have an Oak application, and I'd like to test the main

const app = new Application()

const app = new Application()

configuration, making sure e.g. that all the routes are being found, etc.

I've only been able to find

createMockContext

createMockContext

, etc., but I can't figure out how to make a "mock server request" that would be accepted by

Application.handle

Application.handle

basically?
