Confusion about scrolling

I haven't been able to find what the final word on scrolling in Android is. According to the python source code, there is a method scroll. But it doesn't work.

According to the Android docs, there's a thing called UiScrollable. But it doesn't work.

According to the appium docs, there's a thing called TouchActions. But it doesn't work.

driver.execute_script("mobile: scroll", {"direction": 'down', 'element': el})
If you do this, you are told that "the method has not yet been implemented".

So what is the final word on scrolling? That it's completely broken? That scroll is supposed to work, and that there is something wrong with my setup?

Commencez par suivre la méthode scroll du client Python et comparez-la à Android UiScrollable, Appium TouchActions et aux points d’entrée mobile: scroll mentionnés dans le rapport. Reproduisez les exemples si possible et documentez quelles approches de défilement sont prises en charge, ce qui échoue et si la méthode signalée comme non implémentée est attendue.
