C# Xamarin.UITest REPL连接被拒绝

我正在Xamarin Studio中使用Xamarin.UITest开始UI自动测试。我正在使用Xamarin提供的基本

CreditCardValidator

项目。我的测试按预期工作，但当我尝试添加行

app.Repl（）时

要查询UI并输入

树

命令（或任何其他命令），我会不断得到错误：

App has been initialized to the 'app' variable.
Exit REPL with ctrl-c or see help for more commands.

我也使用了Xamarin的葫芦框架，我可以使用

控制台

命令查询应用程序。不确定这对Xamarin.UITest不起作用

我正在运行Java 1.7、NUnit 2.6.3和Xamarin Studio 6.0.1（build 9）

您打算在什么上运行测试？它是一个模拟器还是一个物理设备？我在模拟器和物理设备上都试过，但运气都不好。我每天都在与这些神秘的Repl/UI测试部署错误作斗争，但我从来没有见过这种错误。我的第一个猜测是包括互联网许可，但你已经有了。想到的唯一可能的解决方案是：1）拥有最新的开发版本的Xamarin.UITest 2）让IDE进行部署，而不是直接引用APK路径3）在调试/发布模式之间切换（如果在调试中，则禁用共享运行时）4）禁用任何代理、VPN连接或其他服务（即Fiddler）这可能会造成干扰。我会尝试这些建议并让你知道。感谢所有人，除了让IDE进行部署。我不知道该怎么做。有什么建议吗？
