Error when trying to run iOS test

[matthewmturner]

I followed the install directions and have a simulator running with idb_companion but i get the following error when running maestro test test_flow.yaml. Originally I was getting an error about missing java so i installed that with brew.

java.lang.IllegalStateException: No devices found. Select a platform by passing --platform <android|ios> for more details

and this is my test_flow.yaml file.

Actually when i run maestro test test_flow.yaml it causes idb_companion to crash with the following error:

@matthewmturner out of curiosity are you using idb_companion to connect to a simulator or real device?

I'm toying with maestro and have only used sims for the time being which connect + launch the tests successfully. (I say "launch" because that part is true, but actually performing the test steps for me is a different story 😅 ... "

I'm connecting to simulator although I confess I had never used idb_companion before this so maybe I've done something wrong

[rborn]

I'm having a similar issue, no matter if it's a sim or device 🙏

[rborn]

meh, ignore me, I forgot to idb_companion --udid {id of the iOS device} 😢

[alexandlazaris]

@matthewmturner perhaps use a simple example to confirm it's all working and go from there

For my experiment, I used:

• maestro v1.9.0
• iOS simulator v14
• Xcode 14.0.1
• app under test was iMessage

appId: com.apple.MobileSMS
---
- launchApp

[Saad-Bashar]

I am a bit confused how to run the app, My starting flow is not working. I am having this app downloaded on my simulator. But it can not trigger it to start. Android works fine when it gets the apk.

[rborn]

• you need to have idb_companion installed on your computer
• run idb list-targets to find the id of the started simulator ( needs to be in booted state)
• run idb_companion --udid {id of the iOS device} with the id you just found
• in another terminal run maestro test test_flow.yaml (or whatever your test file is named)

Hope it helps :)

I have an issue where this exact crash happening. I figure it out that it was crashing in a iOS 16 SIM (isn't supported yet https://maestro.mobile.dev/troubleshooting/known-issues) So check that versions are < iOS 16

BTW I've downloaded python 3 using the web: https://www.python.org/downloads/

Followed the instructions from https://github.com/facebook/idb to get the UUID of the device (although you can find them using the organiser) but I used the pip 3.10 version instead.

pip3.10 install fb-idb

[rborn]

the issue with ios 16 seems to be on the idb side https://maestro.mobile.dev/troubleshooting/known-issues

[alexandlazaris]

@phynet TLDR - iOS 16 is not yet supported using maestro (view the known issues link above)

Also noting that this comment chain is starting to drift off. @matthewmturner hope idb_companion is treating you well now 🤞

[phynet]

@rborn @alexandlazaris Oops, then is my bad. Sorry for add noise to this channel.

[matthewmturner]

@alexandlazaris thanks for the details. using the minimal test i still have the same issue. i use the following:

• maestro v1.10.1
• iOS Simulator Running iPhone 12 Pro on iOS 14.4
• XCode 13.2.1
• App under test was iMessage (using same test file you provided)

[alexCoding42]

I have also a crash on iOS when I try to launch a test with maestro. It works on Android

My config

• Macbook Pro MacOS Monterey 12.5.1 with M1 Pro chip
• maestro v1.11.3
• iOS Simulator Running iPhone 13 on iOS 15.5
• XCode 13.4.1

What I did

• in a terminal launched idb_companion --udid UDID_OF_MY_PHONE
• in another terminal window launched maestro test ios-flow.yaml
• maestro is able to launch the app through my simulator, I can see the splashscreen
• the app crashes just after the splashscreen and I see a weird message in my terminal, the idb_companion stop running

In the simulator I see this error message

[rborn]

@alexCoding42 this message shows usually when you you don't have metro started

[alexCoding42]

@rborn yes now when I start the metro bundler I don't see this error, but I still face a crash of idb companion when trying to run maestro test ios-flow.yaml Right after the launchApp step idb companion stops running and my test fails

[alexCoding42]

It seems there is an ongoing issue that is being investigated for iOS. I just spoke with some people on the Slack channel, so I guess we just have to wait :)

[matthewmturner]

I had to upgrade my Xcode to 14 to resolve the issue that i originally reported.

[TomasBarry]

@alexCoding42 - were you able to make any progress on that issue? I'm facing the same thing

[alexCoding42]

@TomasBarry I reached the support on the Slack channel of mobile-dev there is an ongoing conversation about it: https://mobile-dev-inc.slack.com/archives/C041FU72T54/p1667904287117889?thread_ts=1666866408.069079&cid=C041FU72T54

When I installed the head version of maestro then uninstalled it and reinstalled maestro latest stable release I was able to run my tests on iOS, weird but it seems to work now.

They are doing some fixes that should be release soon
