Storybook is a development tool that helps you build components in isolation and record their states as stories. Stories make it easy to explore a component in all its permutations no matter how complex. They also serve as excellent visual test cases.
A story records a way your component can be used. That means your complete set of stories is a catalogue of all the important use cases to test in your component.
The simplest testing method is manual. Publish your Storybook or run it locally, then look at every story to verify its appearance and behavior. This is appropriate for smaller Storybooks.
As you add more stories, manual testing becomes infeasible. We recommend automating testing to catch bugs and regressions. A complete Storybook testing strategy combines the following techniques to balance coverage, accuracy, and maintainability:
