Angular 2 is released! With it comes new opportunities for brilliantly authored and well-tested applications! While tests don’t come free, they’re well worth the time and effort — especially for larger or long-lived codebases. We’ll explore the full gamut of Angular 2 testing: What to test, how to test, classifications of tests, and the implications and tradeoffs for each of these decisions. Soon you’ll be ready to `npm test` Angular 2 projects with confidence — no Angular 1.x experience required!
