Code To Reproduce Issue [ Good To Have ]

Not reproducible with sample app.

thanks

The error looks coming from XCTest framework internal. I don't think we can fix it in Appium side since Appium gets data by XCTest framework.

You could try snapshotTimeout in https://appium.io/docs/en/advanced-concepts/settings/ if the cause was timeout to get the snapshot.

[jineshqa]

@KazuCocoa Something like this?

resultCaps.setCapability("settings[snapshotTimeout]", 60);

[jineshqa]

@KazuCocoa Where and how do I update these settings?
https://github.com/appium/appium/blob/master/docs/en/advanced-concepts/settings.md

Are these to be set when running appium server or can be set via code?

Thanks

[KazuCocoa]

Like https://github.com/appium/appium/blob/master/docs/en/commands/session/settings/update-settings.md linked in the settings.md or via capabilities like you commented settings[settingsKey https://appium.io/docs/en/writing-running-appium/caps/

[jineshqa]

What is the minimum version of java_client where this is supported? What should I import?

driver.setSetting is showing error in my IDE.

Thanks

[KazuCocoa]

I don't know Java client, but maybe the latest one has...

[jineshqa]

I tried latest one as well (7.3.0), I am still getting the error setSetting not found.

[KazuCocoa]

What about providing the setting via capabilities as you addressed in https://github.com/appium/appium/issues/14022#issuecomment-594254144 ?
They work the same. If it did not help your case, Appium cannot do anything for the XCTest internal error, unfortunately

[jineshqa]

@KazuCocoa Even if that works it will set for entire session and I do not want that as test execution time will increase exponentially.

This is not XCTest issue, this works fine with XCUITest from Xcode. This issue is because WDA is slow on pages with 400+ links, which can be worked around using the settings mentioned but java_client is not letting me use setSetting method. So this is java_client issue. If java_client works and WDA does not respond to it them it becomes WDA issue.

[KazuCocoa]

Okay, so this issue is cannot call setSetting API. Renaming,

hm, Java client seems to have the API
https://github.com/appium/java-client/search?q=setSetting&unscoped_q=setSetting

By Settings API was improved to accept string names. #1240, the key accepts String.

Thanks @KazuCocoa

@mykola-mokhnach I'm seeing an issue with webdriveragent. What is the best way to log the same?

[jineshqa]

@KazuCocoa @mykola-mokhnach Could any java_client dev guide me?
