How to test HTTP endpoints in namek 2.14.1

Question

I am beginner to Nameko framework. I have a very simple Serivce with one GET & POST endpoint, which works as expected when i run locally.

I am trying to create a test case for my Nameko service and I cant seem to find a documentation which explains clearly how I can go about it.

from nameko.web.handlers import http
import json


class SampleService:
    name = "sample_service"

    @http("GET", "/health")
    def health(self, request):
        return 200, json.dumps({'status': "healthy"})

    @http("POST", "/create")
    def create_user(self, request):
        data = request.get_json(force=True)
        print(data)
        return 200, json_dumps({'status': 'created'})

The Best reference I had for testing this was https://github.com/nameko/nameko-examples/tree/master/gateway/test/interface and I am not entirely sure if this code is up todate and can be easily replicated.

Any help on this would be much appreciated.
