Testing

There is no need to mock aiogqlc in your tests. Instead you might want to mock your GraphQL backend. This can be done by providing a aiohttp.web.Application.

The following example shows an example based on pytest, pytest-asyncio, and pytest-aiohttp using a mock GraphQL backend:

import aiohttp
import aiohttp.web
import pytest

from aiogqlc import GraphQLClient


class DemoGraphQLView(aiohttp.web.View):
    async def post(self):
        return aiohttp.web.json_response({"data": {"ping": "pong"}})


@pytest.fixture
async def graphql_client(aiohttp_client):
    app = aiohttp.web.Application()
    app.router.add_route("*", "/graphql", DemoGraphQLView)

    graphql_session = await aiohttp_client(app)
    return GraphQLClient(endpoint="/graphql", session=graphql_session)


@pytest.mark.asyncio
async def test_ping_query(graphql_client):
    response = await graphql_client.execute("query { ping }")
    assert await response.json() == {"data": {"ping": "pong"}}

In fact, the aiogqlc test suite itself is based on this approach. Take a look at the aiogqlc tests directory for more advanced examples.
