Descripción

Description

When using UI automation suite like Maestro, on Android it uses AccessibilityNodeInfo isVisibleToUser method to determine if the element is visible to the user and clickable.

Despite an element rendered with position: absolute and no overflow: hidden on the parent being visible on the screen, the isVisibleToUser flag is incorrectly set to false if the element is outside of the bounds of the parent, causing E2E test to fail (mobile-dev-inc/maestro#1609)

Steps to reproduce

Clone the repro repository first.

To reproduce the issue:

  1. Install the packages with yarn or npm
  2. Open Android emulator
  3. Run yarn android / npm run android
  4. Make sure the app is visible
  5. Press on the dropdown to open it

Then:

  1. Install maestro locally
  2. Run maestro -p android test maestro.yml and see the test fail
  3. Run maestro hierarchy and see that the dropdown items are not visible in the output

Línea de trabajo

Comience con el reproducer obligatorio de PositionAbsoluteBug e inspeccione la salida de accesibilidad de Android para el dropdown renderizado fuera de su elemento padre. Rastree cómo se determina AccessibilityNodeInfo.isVisibleToUser para este caso y, a continuación, verifique que los elementos del dropdown aparezcan en la maestro hierarchy y que el test de Maestro pueda interactuar con ellos sin overflow hidden.
