Making JavaScript Tests Fast, Easy, and Friendly
summary
Advocates building test infra up front, automating runs from the command line and wiring CI into GitHub and Slack, and using Mocha + Chai for readable assertions with Sinon.js to fake XHR and timers so suites run under 30 seconds (aim 5s) — example: replace setTimeout with fake timers and call clock.tick to simulate 5 minutes instantly. Provide hello world test skeletons and onboarding docs, measure slow tests (51ms warning, 300ms red, 2001ms timeout) and prefer fakes over network waits.
