A unit test walks into a bar
summary
Claims that unit tests cut manual testing, lower cost of change, and act as living docs; demonstrates JavaScript examples using Jasmine and DOM helpers like enzyme or vue-test-utils; shows concrete techniques: dependency injection with a fake fetch that returns a resolved promise, and stub/mock/spy patterns to force paths and assert calls; surprises include playful counts like 2.5 billion beers used to illustrate edge, happy and sad paths; recommends gating merges on green tests and fixing flaky tests.
