Question

在以xamarin形式进行单个UI测试时如何禁用位置（我正在使用Android 8.1模拟器）？在一个测试用例中，我要取消位置许可，而在另一个测试用例中，我要模拟GPS找不到用户位置。我想到了背叛者，但在msdn和堆栈（某些链接粘贴在下面）上没有发现有用或最新的内容。

我已经尝试过类似的事情（以及更多类似的“突变”）：

Droid.MainActivity:

[Export("GpsBackdoor")]
    public void GpsBackdoor()
    {
        Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
        intent.PutExtra("enabled", Java.Lang.Boolean.False);
        SendBroadcast(intent);
    }

UITests.Test:

[Test]
    public void SetCurrentUserLocation_WhenGPSisOff_ShouldShowAlert()
    {
        app.WaitForElement(x => x.Text("Nearest stops"));
        app.Invoke("GpsBackdoor");
        app.Tap(x => x.Text("Nearest stops"));

        var result = app.WaitForElement("Could not obtain position");
    }

运行测试后，我收到消息：

System.Exception : Error while performing Invoke("GpsBackdoor", null)
----> System.Net.Http.HttpRequestException : An error occurred while sending 
the request.
----> System.Net.WebException : The underlying connection was closed: The 
connection was closed unexpectedly.

我还尝试关闭Wifi或蜂窝数据，这给了我同样的错误。

我将不胜感激。
