Mastering Node.js Test Runner
watch on portal.gitnation.org ↗https://portal.gitnation.org/contents/mastering-nodejs-test-runnersummary
An introduction to the Node.js Test Runner (shipped in the Node.js binary) covering its built-in features and workflows: filtering tests by name pattern, subtests, marking, watch mode, reporting (including custom reporters), code coverage, parallel testing and sharding across machines, test hooks, mocking, and TypeScript support. The workshop demonstrates using the runner as a fast, simple test harness and a foundation for other libraries; attendees need Node.js 20 (or 20.9 LTS) and Git to follow along.
