--- title: 'Interaction testing with Storybook' --- Stories are useful for verifying the known states of a component. But sometimes you need to test how a component changes in response to user interaction. Stories are convenient **starting points** and **harnesses** for interaction tests using end-to-end tools like [Enzyme](https://enzymejs.github.io/enzyme/) and [Cypress](https://www.cypress.io/). Luckily, this is straightforward. Point your interaction testing tool at Storybook’s isolated iframe [URL for a specific story](../configure/sidebar-and-urls.md#permalinking-to-stories) then execute the test script as usual. Here’s an example using Cypress: ```js // My-component_spec.js describe('My Component', () => { it('should respond to click on button with warning', () => { cy.visit('http://localhost:6006/iframe.html?id=my-component--basic-story’); cy.get('#button').click(); cy.get('#warning').should('contain.text', 'You need to fill in the form!'); }); }) ```
