# Preview a Flow

Testing ensures your viewers get the experience you intend. Preview your scenes and flows to check that personalization, logic and design work perfectly.

1. **Open the flow** – Navigate to your project and click the 'Watch Flow' button.
2. **Choose preview mode** – Select 'Single Scene' to focus on a specific part of your flow or 'Full Flow' to watch the entire experience.
3. **Enter sample data** – Manually enter values for data fields (e.g., name, status) or use random test data to see how personalization looks.
4. **Switch devices** – Toggle between desktop and mobile views using the device icons at the top of the preview window.
5. **Test branches** – Click through different options to follow each branch. Make sure conditions lead to the right scenes.
