Running patrol test on real iPhone device gives me a connection error. Anybody know why?

[SamirKharchi]

Hi there,

I have already searched extensively for a solution or the cause for my issue but I cannot find anything that helps.

I have a flutter app with a real iPhone 14 device (iOS 18.5) and I am running the following command:
patrol test integration_test/patrol -d 00008120-001E3C2E2E60C01E --release --flavor=development --verbose

I can start the tests just fine on a simulator. I can run the app just fine on the physical device. But running the patrol tests on the physical device doesn't work.

Here is what happens
My app is built, the tests start, the splash screen pops up, then right after the splash screen (I don't even see the home page of my app), the app shuts down, the test is shown as failed. Looking into the logs it shows this:

I didn't wanna add this as a real GitHub issue as I am not sure if it's a patrol issue per se.

So, I see a lot of connection errors logs. However, I am not sure I understand why these appear. The device is in development mode, with UI Automation activated. It's correctly paired and identified in/by Xcode. The build looks fine too.

So I am puzzled as what it can be. Does anybody have an idea what the issue is or how I can fix this? This is so annoying.

Thanks a ton iA

Btw. the patrol page says here: https://patrol.leancode.co/documentation/physical-ios-devices-setup

that the bundle identifier should end with .RunnerUITests.xctrunner, is that hard coded or just an example? Will it not work if my identifier ends with say .RunnerUITests.tests?
