我创建了一个简单的 Xamarin.Forms(Portable) 项目并在其中包含 UI 测试项目。但是当我试图在物理设备中运行测试时，它给了我下面提到的异常。

Test Name:  AppLaunches
Test Outcome:   Failed

您在使用ModernHttpClient吗？如果您想处理网络异常，也可以使用Polly 。例如：

conferences = await Policy  
      .Handle<WebException>()
      .WaitAndRetry
      (
        retryCount:5, 
        sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))
      )
      .ExecuteAsync(async () => await getConferencesTask);

AsyncErrorHandler也是处理异步异常的好工具
