ios - (使用 Swift 进行 UI 测试)获取事件应用程序列表失败 : AX error -25205

Question

我们的测试工作完美，但没有明显的原因(检查提交)，UI 测试只是停止在模拟器中工作(尚未在设备上测试)。每次它需要对 UI 组件执行操作(如 tap() 或 typeText("string here"))时，我们都会在标题中收到错误，无法获取事件应用程序列表:AX 错误 -25205。

这是一切出错时的日志:

我发现有类似问题的人，但他们似乎都没有找到解决我们案例的方法:

结果 1:

https://forums.developer.apple.com/thread/47696

Solution: Installing El Capitan and updating Xcode; we are already in El Capitan, and our Xcode is the latest version according to the App Store app.

结果 2:

iOS UI Testing : Failure getting list of active applications: AX error -25205

Solution: None of the answers give a solution.

结果 3:

UITesting Failure getting list of active application

Solution: "Enable UI Atomation" on the device (Settings > Developer). It's already enabled in the Simulator.

我的 Xcode 版本是 7.3.1 (7D1014)，OS X 版本是 10.11.4 (15E65)。

有人知道如何解决这个问题吗？也许将 El Capitan 更新到最新版本？

Answer 1

[Mobile_iOSUITests.LoginViewControllerUITest testLoginComSucesso] 

似乎是真正的原因。您确定调用的方法是否正确，因为方法名称 testLoginComSucesso 中有拼写错误？

因为跟随抛出异常

[NSObject(NSObject) doesNotRecognizeSelector:]

您的 LoginViewControllerUITest 似乎无法识别该方法
