## Testing Apps

After changes are made to an app, testing allows you to validate those changes in the browser before publishing.

### Testing an App

1. Select the **Preview** button in the UiPath Apps Studio header.
2. A new browser tab opens, showing the updated version of the app.
   :::note
   Each time preview is clicked, a new browser tab opens. The most recent tab is the furthest to the left.
