【问题描述】：

我在 Mac OS X 上使用 Appium 1.3.6，并用 C# 编写测试。我在我的测试初始化中添加了 autoAcceptAlerts 能力参数，所以它看起来像这样：

Console.WriteLine("Connecting to Appium server...");
capabilities = new DesiredCapabilities();
capabilities.SetCapability(CapabilityType.BrowserName, "iOS");
capabilities.SetCapability(CapabilityType.Platform, "Mac 10.10");
capabilities.SetCapability(CapabilityType.Version, version);
capabilities.SetCapability("deviceName", device);
capabilities.SetCapability("autoAcceptAlerts", true);

driver = new IOSDriver(new Uri("my-appium-URL"), capabilities);

Console.WriteLine("Connection established.");

而且添加后，我只能偶尔成功启动测试。大多数时候我看到应用程序启动，警报关闭，主要活动显示，但随后测试失败。我在日志中看到的是：

Given I start app for iOS 8.1 on iPad Retina
Connecting to Appium server...
-> error: The HTTP request to the remote WebDriver server for URL <my-appium-URL> timed out after 60 seconds.

并且来自 Appium 日志：

所以，au.mainApp().getTreeForXML() 没有被及时评估。如果我从 init 中删除 autoAcceptAlerts 参数，我需要手动关闭警报，但评估会在一秒钟左右后进行，并且测试运行良好。

也许有人偶然发现了类似的问题，并对正在发生的事情有所了解？真的很感激。

【解决方案1】：

经过一段时间的反复试验，我更换了

capabilities.SetCapability("autoAcceptAlerts", true);
driver = new IOSDriver(new Uri("my-appium-URL"), capabilities);

与

driver = new IOSDriver(new Uri("my-appium-URL"), capabilities);
driver.SwitchTo().Alert().Accept();

一切正常。不过，很高兴知道为什么 autoAcceptAlerts 会导致这个问题，但现在我很高兴。
