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。但是当我尝试在物理设备中运行测试时，它给了我下面提到的异常。

最佳答案
您是否正在使用 ModernHttpClient ？ 您也可以使用Polly如果你想处理网络异常。 例如:
conferences = await Policy
.Handle<WebException>()
.WaitAndRetry
(
retryCount:5,
sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))
)
.ExecuteAsync(async () => await getConferencesTask);
还有AsyncErrorHandler是处理异步异常的好工具
关于xamarin - System.Net.Http.HttpRequestException 异常将在物理设备上运行 xamarin UI 测试，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40188774/
