Xamarin UITest:正在安装DeviceAgent，但未运行.APP和测试

我目前正在进行一个项目，使用Xamarin UItest测试IOS应用程序。我将解决方案配置如下。但是，在物理设备和虚拟设备上执行测试用例时，我遇到了错误。我想知道我的配置有什么问题，或者我遗漏了什么？DeviceAgent正在安装中，但在此之后什么也没有发生

using System;
using System.Threading.Tasks;
using Xamarin.UITest;
using Xamarin.UITest.Queries;

namespace Testframework_DitApp
{

    public class AppInitializer
    {

        public static IApp StartApp(Platform platform)
        {

            if (platform == Platform.iOS)
            {
                return ConfigureApp
                    .iOS
                    .Debug()
                    .EnableLocalScreenshots()
                    .DeviceIdentifier("8b7937ef87210a797fc4fa0750e3c62d194bd5b1")
                    .InstalledApp("/Users/R/Stack/Developer/Testframework_DitApp/Payload/Prod.app")
                    .StartApp();           
            }
            return ConfigureApp.iOS.InstalledApp("/Users/R/Stack/Developer/Testframework_DitApp/Payload/Prod.ipa").DeviceIdentifier("8b7937ef87210a797fc4fa0750e3c62d194bd5b1").StartApp();
           }
    }
}
