apollo-server-tests SKILL.md skillA
apollo-server-tests from testland/qa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Wraps Apollo Server testing patterns: `server.executeOperation()` (in-process, no HTTP), `supertest` against an ephemeral-port HTTP server (port 0), context injection via the `contextValue` second-argument, and assertion patterns for response shape + errors. Includes the production-config gates testable through this skill - introspection-disabled, persisted-query mode, hideSchemaDetailsFromClientErrors. Use when writing tests for an Apollo Server v4+ GraphQL service.
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
# apollo-server-tests
## Overview
`executeOperation` initializes automatically - no startup needed for
unit-style tests against the schema in-process. For HTTP-layer tests
(CORS, middleware, response headers), use `supertest` against an
ephemeral-port server.
## When to use
- Unit tests for resolvers using `executeOperation`.
- Integration tests for HTTP-layer behaviour using `supertest`.
- Production-config gates: assert introspection / APQ /
hideSchemaDetails settings match your production config.
## Authoring
### Install
```bash
npm install --save-dev @apollo/server supertest @types/supertest
```
### In-process tests with `executeOperation`
```typescript
import { ApolloServer } from '@apollo/server';
import { typeDefs, resolvers } from './schema';
const testServer = new ApolloServer({ typeDefs, resolvers });
test('returns greeting', async () => {
const response = await testServer.executeOperation({
query: 'query SayHelloWorld($name: String) { hello(name: $name) }',
variables: { name: 'world' },
});
// Parse/validation/execution errors surface in `errors`, not thrown
if (response.body.kind !== 'single') throw new Error('expected single');

How to install
mdr add testland/qa/apollo-server-tests@sha256:a9d112e42492bb36The line at the top of this page pins the label git:20260724.d4db756, 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.
