Jest & Enzyme-testing your React application

on YouTube ↗06m

" summary

Jest provides zero configuration unit testing with built‑in assertion, mocking and coverage tools, and pairs with Enzyme for React rendering and interaction checks; use shallow vs mount to isolate components or exercise children, use jest.mock to replace APIs, and rely on snapshot testing (watch mode lets you press u to update) with a snapshot-diff option to show only changes so tests stay focused rather than brittle giant JSON blobs.
