Virtual Screen Reader

The Guidepup Virtual Screen Reader is a headless screen reader for unit test automation.

  • Mirrors Screen Reader Functionality - simulate and assert on what users can do when using screen readers.
  • Test Framework Agnostic - run with Jest, Vitest, Web Test Runner, in Storybook, as an independent script, no vendor lock-in.
  • UI Framework Agnostic - want to use React, Vue, Solid, Svelte, etc.? All good here! Works with any UI framework, and plays nicely with the Testing Library suite.
  • Fast Feedback - avoid the cumbersome overhead of running an e2e test with a real screen reader by running virtually over the provided DOM.


This package should not replace but augment your screen reader testing, there is no substitute for testing with real screen readers and with real users.
