Developers spend 21% of their time fixing bugs. Debugging UI appearance can be especially frustrating. Reproductions require you to spin up different browsers, get your app into the right state, and trudge through DOM. The stakes are higher too; uncaught bugs cost 5-10x more time to fix in production than in QA.
It's common sense then that thousands of frontend teams visual test using Storybook. Storybook helps you build components and write visual tests. Running tests at the component level allows you to pinpoint the root cause of a bug. Taking image snapshots helps you catch regressions automatically. That means folks can ship UIs without worrying about stowaway bugs.
This guide introduced you to the basics of visual testing. Tom and I hope you can build upon these learnings in your own projects. Join the Storybook mailing list to get notified of more helpful articles and guides like this.
