Test Node.js HTTP APIs in-process with SuperTest — request(app) without binding a port, chained .expect assertions, auth headers, JSON body validation, and Jest integration with proper async/await patterns.

From the source SKILL.md

This skill makes an AI agent write integration tests for Express/Koa/Fastify-compatible Node HTTP apps using SuperTest: pass the app object directly to request() so no port is bound, chain .expect() for status/header checks, and assert response bodies with Jest matchers. Trigger it when a Node project exposes an Express app, when the user asks to test REST endpoints without spinning up a server, or when supertest is already in devDependencies.

What this skill does

SuperTest API Testing is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/supertest-api/ and loads when your prompt matches the skill's trigger.
