Document React component states in Storybook by creating a co-located `.stories.tsx` file using CSF3 meta configuration. Define one named story per meaningful UI state, such as default, loading, error, or disabled, to keep visual documentation and implementation in sync.

Write interaction tests for Storybook stories by adding optional play functions to your CSF3 story exports. Use Storybook test utilities inside the play function to query elements by accessibility roles and assert expected behaviors like clicks or typing without duplicating render tests.

Configure CSF3 meta and decorators by exporting a meta object with component metadata, then apply decorators to standardize wrapper context. Define shared args within the meta or individual stories to inject reusable properties and layout providers across your React component variations.

Storybook handles UI state documentation and interaction testing through play functions, verifying component behaviors visually. For separate logic testing, the recommended strategy splits UI verification to Storybook and underlying logic testing to vitest, ensuring complete component coverage without duplication.

Create separate stories for React component edge cases to improve stateful coverage completeness. Defining one story per meaningful UI state, including loading, error, and disabled variations, makes component behavior explicit and reviewable during development, reducing uncertainty about how components look and behave.
