MIT-licensed open-source library Free Node.js HTTP server testing library github.com · 5 Oct 2026

Purpose: SuperTest provides a high-level abstraction for testing HTTP while allowing access to SuperAgent’s lower-level API.
Target use: The project describes itself as a library for testing Node.js HTTP servers with a fluent API.
Installation: The README says to install it as an npm development dependency with `npm install supertest --save-dev`.
Server setup: You can pass an HTTP server or a function to `request()`, and a server that is not listening is bound to an ephemeral port.
Test frameworks: The README says SuperTest works with any test framework and shows a Mocha example.
Assertions: The API supports assertions on response status, body, headers, and custom functions.
Protocol: The README shows HTTP/2 enabled through options passed to `request()` or `request.agent()`.
SuperAgent features: The README says SuperAgent methods are available, including multipart file uploads, and gives `.field()` and `.attach()` examples.
Async usage: The examples show callback, promise, and async/await styles for making requests and checking responses.
License: The repository lists the project license as MIT.
Security reporting: The security policy asks users to report vulnerabilities by email rather than through public GitHub issues, discussions, or pull requests.
Maintainer: The repository says SuperTest is maintained for Forward Email and several other projects, including Lad, Spam Scanner, Bree, Cabin, and Lass.
