Built-in Tests with Node.js

on YouTube ↗27m

" summary

A new built-in testing module node:test exists, imports require the runtime prefix and it supports CJS and ESM; migration from mocha is straightforward and a real project with five test files moves over in about eight months of use. Output formatting changes land in Node 20.2, and the runtime adds conveniences like test.skip/test.todo/test.only. The npm test (npm module) lets teams pin behaviour while upgrading, and the module is already used in production sites and packages.
