Deterministic Mocking with GraphQL and Apollo Lunar Launch
summary
Shows a concrete solution: Apollo Server plus a tiny mocks file gives realistic fake data but couples tests to defaults, so ezCater built Lunar deterministic GraphQL mocks to seed Apollo Server per test. Demo uses Apollo Engine, react-test-renderer, MockProvider and Cypress end-to-end with Apollo Server to drive integration specs. Tests change a mock list from mock list default 5 -> test 2, assert exact names and mutation roundtrips, and demonstrate determinism — the live demo fails then is fixed, proving it works.
