Shipping UI with Confidence: Storybook + Contract Tests

How to stop UI regressions before they hit users.

Treat components as products: document their states, mock the API contract, and record visual snapshots. Visual testing catches rendering drift; contract tests fail fast when backend responses change. Accessibility checks run alongside stories to keep usability non-negotiable.
This workflow decouples teams and unlocks parallel delivery. UI becomes stable, testable, and fast to evolve.
