Last verified Sep 9, 2026 against supertest@7.2.2.

supertest ships CommonJS only. require("supertest") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=14.18.0. import "supertest" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("supertest") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=14.18.0.
2. From ES modules use the default import: import supertest from "supertest"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/supertest
