App Testing¶
Changes to UI or scripts in Lucy Studio can be verified on connected test devices.
You can update all devices at once or run different pages on individual devices.
Update All Devices¶
Use this flow to push the latest screen to every connected test device.
- Edit: Update UI or scripts.
- Select page: Choose the page to run.
- Save: Press Cmd + S.
- Run: Click Run (triangle icon) in the upper-right corner.
- Verify: Confirm all devices receive the latest UI and scripts.

Test Devices Independently¶
Use this flow when each device needs a different page or scenario.
- Select page: Choose the page for a specific device.
- Open device list: Click the phone icon to open
Device sync. - Run per device: Click Run (triangle icon) for the target device.
- Repeat: Change page and run again for other devices.

If UI or Scripts Do Not Update¶
If updates do not appear, force synchronization for missing resources.
- Open Sync menu: In
Device sync, click the sync button next to the target device. - Select assets: Check assets to sync (Page, Image, Theme, Component, Script, etc.).
- Run sync: Click the sync button in the popup.
- Retest: Click Run (triangle icon) again on the device.

FormContainer Sync Order¶
When syncing pages that include Form widgets, keep this order to preserve data structure.
- Sync order: Sync child pages first, then sync the top-level parent page.
- After first sync: You can usually test by syncing only the parent page (unless you need isolated child-page testing).
