Can Maestro run the same test concurrently on one Android device and one iOS device?

[loijwdev]

I’d like to ask whether Maestro supports running the same test flow at the same time on two different platforms, specifically:

1 Android device

1 iOS device

My goal is to execute the same test concurrently for cross-platform validation (for example in CI).

If this is supported:

What is the recommended setup or command?

Are there any limitations or best practices?

If not:

Are there any suggested workarounds (e.g. parallel CI jobs, separate Maestro processes)?

Thanks in advance for your help 🙏

There's no way to run Maestro flows on physical iOS devices
That might change in the future, but currently, it only works on iOS emulators.
For running concurrently, you can use the parameter "--shard-all 2" when you run Maestro on your command line .

Oooh, I haven't tried sharding across platforms! Does that work?

In my case, running tests with --shard-all 2 works only when there are two iOS simulators or two Android devices available. It does not work when iOS and Android devices are used together simultaneously.
