Maestro stopped asking which device to use when many are running, defaults to the first one

[DavidREntwistle]

Is there an existing issue for this?

• I have searched the existing issues and didn't find mine.

Steps to reproduce

Steps to reproduce:

1. Open multiple devices e.g. x1 iOS simulator & x1 Android Emulator.
2. Run the maestro test yourFlow.yaml command.
3. Observe no Multiple running devices detected. Choose a device to run on. prompt.

Actual results

When I have multiple devices running, I cannot select which device to run the flow on with the maestro test command anymore.

If I have both an iOS simulator and android emulator running and I want to run X flow on the android emulator, I need to close the iOS simulator first, vice versa.

Expected results

When I have multiple devices running, I should be prompted with:

Multiple running devices detected. Choose a device to run on.
Enter a number from the list above:

The maestro studio command still allows this functionality.
I do not require any devices to be closed to run X flow on the correct device.

I confirm this issue occurs on (tested on v1.37.4).

I verified this is a regression introduced in #1732 (commit dc1c0fa).

The issue does not occur on the commit right before it: 5f994da

The workaround is to pass the ID of the device that you want to run on. It works when you have multiple devices connected.

maestro \
  --udid emulator-5554 \
  test <my_flow_path

To see device IDs, run:

• Android: adb devices
• iOS: xcrun simctl list devices booted

I've noticed whilst attempting to run a flow on an iOS simulator the error (Unable to launch app xxxxxxxxxxxx: Package xxxxxxxxxxxx is not installed) occurring. This only occurs when I have both an Android emulator and iOS simulator device running and then attempt to run an iOS flow (with iOS specific app id).

I believe this is because it's attempting to launch the iOS specific flow on the Android emulator rather than the iOS simulator.

Fixing this issue should resolve this as when we have multiple devices running, as we should be prompted with:

Multiple running devices detected. Choose a device to run on.
