Markdown-driven end-to-end tests for Relay. Each test is a self-contained .md file that defines a GraphQL server (via Grats), a Relay-powered React component, and optional interaction steps. The test harness extracts the code blocks, compiles them with Grats + relay-compiler, renders with React Testing Library, runs interactions, and snapshot-tests the output.
Tests run against Relay runtime packages from source, so changes are reflected immediately without a build step.
