# Testing

These guides show you how to test the server-side behavior of Flow applications using browserless tests. Start by [choosing the setup for your application framework](https://vaadin.com/docs/next/building-apps/testing/browserless.md#choose-your-framework), then choose a guide for the behavior you need to verify.

Browserless tests run against Java components without a browser. Use browser-based tests when you need to verify rendering, client-side behavior, or real browser interactions. See [the testing reference](https://vaadin.com/docs/next/flow/testing.md#comparison) for a comparison of the approaches.
