Happo is a visual regression testing tool. It hooks into your CI environment to compare the visual appearance of UI components before and after a change. Screenshots are taken in different browsers and across different screen sizes to ensure consistent cross-browser and responsive styling of your application. The first thing you want to do is to set up a test suite for Happo. A test suite consists of a set of components and variants of those components. There are many ways to do this, and it all depends on your existing tech stack, your application, your experience with other test frameworks, and more.

Features

  • A Storybook application can serve as the test suite driver for Happo
  • By using the Static bundle integration, you can bring your own javascript bundle and have full control over the build phase and execution
  • By integrating Happo with Cypress or Playwright, you can turn your end-to-end tests into a Happo test suite
  • If you want to test an existing (public) website, you can use the pages option
  • If you want to create a custom test suite for React or other js framework apps, you can use Happo Examples
  • For native apps and others not running in a browser, use the API directly
