[KazuCocoa]

it could indicate that the InstrumentService to launch XCTest process had an issue. https://github.com/appium/WebDriverAgent/blob/fb7932255359460b6962b14abada08ca70333195/lib/webdriveragent.js#L403

The reason could vary. Does it occur only on a specific device, OS version etc?

[erdncyz]

Hi @KazuCocoa,

ı have 3 different devices which are ; iPhone 11 Pro Max v 17.2.1 iPhone 11 Pro v 16.0.3 iPhone 11 v 17.5.1

Also machine the same so these devices are connected the same machine(Mac Mini) ı encounter all of the devices. Sometimes, all of them are okay, but sometimes one device is okay at that time, and other devices are not okay.

[KazuCocoa]

The issue is not device/os specific but perhaps connection-related between the host and each device then. I assume this is kind of random XCTest session failure because of the device side internal reason.

Will the device reboot reduce the frequency?

Hi @KazuCocoa

ı tried my all devices' connection and reboot my all devices but ı encounter still this error sometimes. Why is wda upload each session? If wda was installed once and used it all the time, this wouldn't be a problem. is this possible ?

[KazuCocoa]

Appium doesn't re-install since the caps have usePreinstalledWDA: true. https://appium.github.io/appium-xcuitest-driver/latest/guides/run-preinstalled-wda/ is what you do. Then, Appium launches the preinstalled bundle id.

If it occurs sometimes only, the main reason could be the iOS internal, which means only Apple can improve it. We probably could guess possible reasons by checking the device log, but probably no good solution by outside Apple people. Based on my experience, iOS 17 is more unstable than iOS 16 in terms of keeping device connection.

(I guess failed to start XCTest session, or xctest session got disconnected by testmanagerd, which is iOS internals' deamon for testing, stuff etc.)

[KazuCocoa]

Or possibly you could use 3rd party tools to launch WDA https://appium.github.io/appium-xcuitest-driver/latest/guides/attach-to-running-wda/ and attach the WDA as more advanced method. For iOS 17+, it will not use Apple tools to start the WDA. I'm not sure how it will be stabler though.
