Add integ test for http server

[bhuber]

Overview

This fixes #40 , hopefully satisfactorily. The intent here is to make a generic and flexible test harness for exercising the gofail http api. I've added some obvious basic tests; I'm sure the maintainers can think of more to add in the future. I also fixed several inaccuracies in the documentation, and added a few missing pieces I found during the course of implementation.

The code should be pretty self explanatory. The main explanation of the test setup is in the godoc for TestAll in integration/server/server_test.go .

This is my first PR to this repo, and I did my best to follow all the contribution instructions I could find, but please let me know if I missed anything.

Testing

• make run-all-integration-tests works locally
• I ran the github actions in my fork, here's the passing integration test run: https://github.com/bhuber/gofail/actions/runs/13305753815
