Interactive UI testing in Storybook uses play functions to simulate real user interactions like clicks and typing, combined with MSW network mocks and global decorators to validate component behavior under realistic conditions.

Yes, you can mock network requests in Storybook component tests using MSW to simulate success, loading, and error scenarios, ensuring your interactive play functions accurately validate network-dependent user flows.

Yes, running play function tests requires Storybook 7+ with @storybook/addon-interactions installed, along with MSW and global decorators configured to simulate real user flows and global contexts.

Test theme and router contexts in Storybook by applying global decorators and state seeding to your stories, ensuring that interactive components relying on these global contexts are evaluated under realistic test conditions.

Limitations of play functions for UI testing include the requirement to enforce at least one assertion per test and the strong discouragement of placing business logic inside tests, keeping them focused purely on UI interactions.

The best way to test form submissions in Storybook is coordinating play functions for user input events with MSW mocks for network responses, validating the complete flow from data entry to submission feedback.
