Xamarin UITest does not clean my app on iOS

llaurenss

Hi all,

When I ran my tests on android the app always starts at the beginning and no prev configurations are set. But with iOS the app always starts with the page where it last has been. So when I ran test A and i'm on screen X and after that I ran test B then the app will start at screen X instead of the initial beginning screen.

I already set the AppDataMode to clear but this didn't do the trick.

Thanks in advance!

I was just able to verify this issue with a simple Xamarin.Forms app. I reached out to see if this is a known issue or not.

Turns out it is a known issue and the workaround is to set an Environment variable in the AppInitializer, e.g.:

public class AppInitializer
{
    public static IApp StartApp(Platform platform)
    {
        if (platform == Platform.Android)
        {
            return ConfigureApp.Android.StartApp();
        }

        Environment.SetEnvironmentVariable("UITEST_FORCE_IOS_SIM_RESTART", "1"); // <----  Add this line

        return ConfigureApp.iOS.StartApp();
    }
}
