You can test it in iOS simulator, If you get the same issue.

Do you use return ConfigureApp.iOS.DeviceIdentifier("xxxxx").AppBundle("/path/to/App.app").StartApp(); to start uitest? If not, please share your code about starting UItest.

return ConfigureApp.iOS.InstalledApp("com.companyName.AppName").StartApp();
When I run UITest using physical device, agent runner is not getting installed in my device.

return ConfigureApp.iOS.DeviceIdentifier("xxxxx").AppBundle("/path/to/App.app").StartApp();
When I run UITest using simulator I am able to install device agent in simulator device.

By using:

.InstalledApp(bundleid).DeviceIp(ipaddress)

instead of:

.AppBundle(PathToIPA)

in the

ConfigureApp

I tried with

if (Platform == Platform.iOS)
{
app = ConfigureApp
.iOS
.WaitTimes(new WaitTimes())
.EnableLocalScreenshots()
// Used to run a .app file on an ios simulator:
//.AppBundle("path/to/file.app")
// Used to run a .ipa file on a physical ios device:
.InstalledApp("com.companyName.appName")
.DeviceIp("xxx.xxx.x.x")
.StartApp();
}

Still I am getting error failed to install device agent Exit Code 5.

If you want to run UI test in the iPad, You can use .ipa in the .AppBundle("path/to/xxx.ipa"). not the path/to/file.app

I want to run UITest case in my physical device i.e. iPAD not on simulator.

As per the documentation,

https://video2.skills-academy.com/en-us/dotnet/api/xamarin.uitest.configuration.iosappconfigurator.appbundle?view=xamarin-uitest-sdk

.AppBundle("path/to/xxx.ipa").. it will force to launch app on simulator.

Sorry, that is my fault, You can use InstalledApp method, please install the app on the phone before running InstalledApp()

   IApp ApplicationContext = ConfigureApp  
                       .iOS  
                       .DeviceIdentifier("device id string as shown in xcode device list")  
                       .InstalledApp("/my/path/to/ipa/file")  
                       .StartApp();

I found a similar thread in SO: https://stackoverflow.com/questions/40537550/xamarin-uitest-deviceagentexception-failed-to-install-deviceagent/40537611#40537611

You can refer to it, If this issue is still existed, because UITest belongs to AppCenter, you can open an issue in the GitHub thread: https://github.com/microsoft/appcenter/issues
