graphql-yoga-tests

Overview

Per the-guild.dev/graphql/yoga-server/docs/features/testing: "Calling the yoga.fetch method does not send an actual HTTP request. It simulates the HTTP request which 100% conforms with how Request/Response work."

Structurally different from Apollo's executeOperation - Yoga's testing path goes through the HTTP transport layer including middleware, headers, and response codes. There is no separate "in-process" vs "HTTP-layer" choice.
