Last verified Sep 9, 2026 against test-exclude@8.0.0.

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