Automated Testing JavaScript

" summary

Explains exactly how to get fast, reliable feedback: set up mocha and chai with karma to run tests in a browser, use a tiny canary test to verify tooling, stub external services with sinon so tests are idempotent, and prefer tests one layer below the UI following the test pyramid. Shows code coverage, a real divide() example and exception and performance tests, and recommends wiring the canary into continuous integration so failures surface immediately.
