 Storybook supports cross-browser visual testing natively using [Chromatic](https://www.chromatic.com/storybook/?ref=storybook_site), a cloud service made by the Storybook team. When you enable visual testing, every story is automatically turned into a test. This gives you instant feedback on UI bugs directly in Storybook.

-#### What’s the difference between visual tests and snapshot tests?
+### What’s the difference between visual tests and snapshot tests?
+
+[Snapshot tests](./snapshot-testing.md) compare the rendered markup of every story against known baselines. This means the test compares blobs of HTML and not what the user actually sees. Which in turn, can lead to an increase in false positives as code changes don’t always yield visual changes in the component.

+Visual tests compare the rendered pixels of every story against known baselines. Because you're testing the same thing your users actually experience, your tests will be richer and easier to maintain.
