Improve unit test coverage for Picker, GeofenceManager, and others (#4233)

google-labs-jules[bot] · web-flow · commit 5c357e52ab23 · 2025-12-12T06:24:44.000+02:00
Added `PickerTest` to cover `Picker` interaction logic (including tablet mode and event handlers) and various inner classes.
Added `GeofenceManagerTest` to cover `GeofenceManager.Listener` and related inner classes.
Added `RemoteControlCallbackTest` to cover `RemoteControlCallback` static methods.
Added `SpinnerNodeTest` to cover `SpinnerNode` rendering logic.
Updated `TestCodenameOneImplementation` to support tablet mode testing.
Ensured all tests use `@FormTest` and run correctly on the simulated EDT.
Fixed threading issues in tests by re-initializing Display where necessary.
