Testing GraphQL: From Zero To Hundred Percent
summary
Practical roadmap for getting to 100% GraphQL test coverage: start with static typing (TypeScript) and unit tests, add integration tests that mock the schema or run an Apollo server with mocks (set mock: true) and exercise queries via Postman, then run end-to-end tests against a real test server. Demonstrates tools like EasyGraphQLTester, Apollo client/provider, Postman and a CodeSandbox full‑stack demo. Shows load testing (50 virtual users, ~1,050 requests in ~10s) and claims mocks plus type checks catch many issues before e2e.
