Write and run markdown-driven e2e tests for Relay. Covers fixture format, server/client code patterns, interaction DSL, snapshots, and running tests.

🧰 Not standalone. This skill ships with facebook/relay and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

Relay E2E Tests

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.
