Appcenter: Xamarin.UITest.XDB.Exceptions.DeviceAgentException : Failed to launch DeviceAgent

[KthProg]

What App Center service does this affect?
Xamarin.UITest

Describe the bug
ExitCode is given as 64. The test output shows that xcodebuild failed with the error "option Destination requires at least one parameter of the form 'key=value'". This suggests that the xcode build destination syntax is incorrect (do I need a specific version of xcodebuild perhaps?)

To Reproduce
Try to connect to an iOS simulator by id, with a .app file given to install.
NUnit 3.12.0
Xamarin.UITest 3.03-dev1
iOS 12.4 simulator
XCode 10.3
Build version 10G8

Expected behavior
The tests run.

Desktop (please complete the following information):

• OS: MacOS
• Version 10.14.5

Smartphone (please complete the following information):

• Device: iPhone 6 Plus Simulator
• OS: iOS 12.4

[KthProg]

Also possible that this is the timing issue in the release notes for Xamarin.UITest? https://www.nuget.org/packages/Xamarin.UITest/3.0.3-dev1

[nielscup]

Same issue here, unable to run UITests on iOS simulator. VS2019, Xcode 10.2 and 10.3. It worked fine before upgrading to VS2019 with Xcode 10.1

[akamud]

Same problem here.

[Oddj0b]

We have a fix available in the latest dev release of Xamarin.UITest, you can get it through your Nuget channels.

[Agitto]

Seems like the issue is successfully fixed in 3.0.4-dev1 but only for .net45 targets. It is still possible to reproduce the issue by referencing Xamarin.UITest 3.0.4-dev1 from netcoreapp2.0. Can it be possible that libraries from Nuget package for 'net45' and 'portable-net45+win8+wp8' targets were built from different sources?

[KthProg]

@Agitto I really hope that's not the case since I'm using .NET Core 2.0 :(

[KthProg]

@Oddj0b I'm still seeing this issue although it is on a .NET Core 2.0 unit test application as @Agitto mentioned.

[Oddj0b]

@KthProg seems like we didn't get rid of the bug. I will talk with the engineers.

[Agitto]

@Oddj0b Any news on this?

[Oddj0b]

@Agitto Is this still an issue with Xamarin.UITest 3.0.4?

[Moshex]

I am on Xamarin.UITest 3.0.4 and I am getting:

is there anything I need to do to stop getting the error?

[manikantasanisetty]

@Moshex I downgraded Xamarin.UITest package to 3.0.3 and started working for me.

[Moshex]

@manikantasanisetty Your suggestion worked, thank you so much! is Xamarin.UITest package to 3.0.4 broken and will it be fixed in Xamarin.UITest package to 3.0.5?

[jbachelor]

@Moshex and @manikantasanisetty - Thanks so much. I'm getting this same issue:

Downgrading to Xamarin.UITest 3.0.3 seems to fix the issue. Should this be reported in a new issue, since the original issue posted here is about a different error?

ExitCode is given as 64. The test output shows that xcodebuild failed with the error "option Destination requires at least one parameter of the form 'key=value'".

[Moshex]

@jbachelor and @manikantasanisetty , I opened a new issue here: https://github.com/microsoft/appcenter/issues/1477 feel free to add to it as needed.

[stoneman]

UITest 3.0.5 has been released. Could you all test with that and let us know whether you are still experiencing any problems please?

[lukashaertel]

@jonstoneman I experienced the bug with 3.0.4, updated to 3.0.5 and now the bug does not appear anymore.

[pontusntengnas]

3.0.5 seem to fix the issue for me

Hi guys, I got :
Xamarin.UITest.XDB.Exceptions.DeviceAgentException : Failed to launch DeviceAgent
ExitCode: 64
on the latest version : 3.0.5 (same for 3.0.6.dev) it is only reproduce only with .net core 3.0. It works fine with net472.

[nielscup]

Xamarin.UITest 3.0.5 solves this issue for me.

[imatviienkoomcinc]

@nielscup Hi man, Are you using .net core 3.0? Here is code I have used in my tests:
if (Platform == Platform.iOS) { app = ConfigureApp .iOS .AppBundle ("../../../iOS/bin/iPhoneSimulator/Debug/test-tests.iOS.app") .DeviceIdentifier("B3708E9D-6781-490F-B28C-EA73C0206EF4") .StartApp(); }

For Android, all works fine but for IOS such trobles.
After the launch, I got the error I mentioned above. I try 3.0.5, it did not help. Maybe you can suggest some additional things for investigations.

[nielscup]

Hi, we use shared lib, no .netcore, and the following config:
ConfigureApp .iOS .Debug() .InstalledApp(iOSBundleId) .StartApp(AppDataMode.DoNotClear);

Where iOSBundleId is domain.com.yourappname.

Also clear your bin and obj folders and uninstall your app after updating config. Then build and deploy your app and try to run your UITest a second time when the first time does not work because sometimes it fails the first time, but works the second (I think this is another UITest issue).

Hope it helps.

[stoneman]

@imatviienkoomcinc UITest does not support .net core

[imatviienkoomcinc]

@jonstoneman Thanks a lot for the clarification. Are you going to support it in the near future? (By the way, it is perfectly work for Android, that's why I had this concern). Thanks in advance for the answer, I really struggle with searching for answer.

[stoneman]

@imatviienkoomcinc The work to add .net core support has not yet been scheduled.

[tarunmittal2012]

@Oddj0b
I am using nunit 3.12 & xamarin uitest 3.0.7
VS 2019 mac os Catalina, iOS 13.3.1 real device *getting exception failed to install device agent.*
I tried with 3.0.7 as well still get this issue.

[sreeneshspai]

@tarunmittal2012 Did you get this fixed?

[chrisweihu]

why is this ticket marked as closed. it is clearly still occuring and not fixed.
