[VegaOS] UIAutomator returns random View IDs instead of assigned Test IDs in Kepler app

Vega Open Beta Q&A
1

Hi everyone,

To perform automation on the Kepler app, we are using the Kepler automation driver (JSON‑RPC) through Appium. Below are the capabilities used:

{

“platformName”: “Kepler”,

“appium:automationName”: “automation-toolkit/JSON-RPC”,

“kepler:device”: “vda://{{device_id}}”

}

Issue: Appium Inspector returns random View IDs and highlights hidden UI elements

While identifying elements, Appium Inspector always returns random/dynamic test_id, even though the development team confirmed that views have been assigned stable Test IDs in this format:

Plain Text

<PackageName>{test_id}

Additionally, Appium Inspector highlights hidden/non-visible UI elements instead of the visible element on the screen. This makes element identification unreliable.

Environment

  • App: Kepler

  • Automation Tool: Appium Inspector using Kepler automation driver (JSON‑RPC)

  • Platform: Vega OS

  • Build: Latest internal build

Description

During UI automation inspection:

  • Returned test_id do not match the assigned Test IDs.

  • IDs appear random and change between sessions and builds.

  • Appium Inspector often hovers over invisible UI elements instead of the visible ones.

This leads to inconsistent or incorrect element identification.

Steps to Reproduce

  1. Launch the Kepler app.

  2. Navigate to any screen with assigned Test IDs.

  3. Open Appium Inspector and inspect visible UI elements.

  4. Observe the returned test_id and highlighted element.

Expected Result

  • The automation driver should return the assigned Test ID:
<PackageName>{test_id}
  • Appium Inspector should highlight the actual visible UI element being inspected.

Actual Result

  • View IDs are random/dynamic, not the assigned Test IDs.

  • Appium Inspector highlights hidden elements instead of the visible ones.

Impact

  • Automation scripts fail across runs due to unstable IDs.

  • Element inspection is inaccurate, blocking reliable automation.
