Authors GraphQL subscription resolver test suites over graphql-ws (WebSocket) and graphql-sse (Server-Sent Events) transports: subscribe to event streams via the async-iterator API, assert emitted data shape and sequence, verify connection lifecycle and protocol close codes, and validate auth-on-connect (connectionParams / authenticate callback) plus resolver-level pubsub trigger logic. Use for real-time subscription operations; not for queries or mutations - for those use apollo-server-tests…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# graphql-subscription-test-author ## Overview Per the GraphQL October 2021 spec (section 6.3, blocked by Cloudflare Turnstile - cite by stable ID "GraphQL October 2021 spec, Section 6.3: Subscription"), a subscription operation must: select a single root field, return an event stream, and emit one result per event. Each emitted result is executed independently against the schema, exactly like a query. This skill covers testing the transport and resolver layers for subscriptions. The two most common Node.js transports are: - **graphql-ws** - WebSocket subprotocol `"graphql-ws"` (per [the-guild.dev/graphql/ws](https://the-guild.dev/graphql/ws)) - **graphql-sse** - HTTP Server-Sent Events (per [the-guild.dev/graphql/sse](https://the-guild.dev/graphql/sse)) Both expose an identical async-iterator surface via `client.iterate()`, making the same test patterns portable across transports. ## When to use - Writing tests for subscription resolvers (pubsub trigger, filter, error). - Asserting connection lifecycle: handshake, auth rejection, protocol close. - Verifying auth-on-connect: `connectionParams` (WS) or `authenticate` …

How to install
mdr add testland/qa/graphql-subscription-test-author@sha256:61ba9280da15b7e5The line at the top of this page pins the label git:20260813.0ecb572, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
