无法在Jenkins中运行Xcode(7.3)UI测试

我试图在我的本地计算机上工作的Jenkins机器上从命令行运行Xcode UI测试。 但是,当我尝试在Jenkins中运行UI测试时,他们似乎无法在模拟器中启动应用程序。 发生的情况是设备在模拟器中加载,UI测试目标打开,屏幕变黑。 然后似乎没有任何事情发生30秒,直到我得到如下错误(我希望应用程序启动并自动开始):

应用程序是否无法启动,因为我的Jenkins机器无法在Xcode隐式未通过测试之前足够快地打开它? 或者是否有通知阻止应用程序启动?

会发生什么是XCTest尝试将Home按钮按下事件发送到设备,但是没有收到完成通知30秒。

我不认为它与通知UIAlertView阻止Home按钮将测试目标发送到后台有任何关系,因为根据我的经验,这样的问题会引发不同的错误消息( "Failed to background test runner within ..." )。

我不熟悉Jenkins解决方案,但如果您怀疑超时太短,可以尝试按如下方式更改它(我找到了一些hacky方式)。

[XCTestDriver _runSuite]添加到先前将运行的代码[XCTestDriver _runSuite] (例如,添加您自己的__attribute__((constructor))函数并将此代码放入其中:

 extern __attribute__((weak)) void* _XCTSetEventConfirmationTimeout(NSTimeInterval); // Change the default 30 seconds timeout. long MY_NEW_EC_TIMEOUT = 120; NSLog(@"Trying to call _XCTSetEventConfirmationTimeout(%ld)", MY_NEW_EC_TIMEOUT); if (&_XCTSetEventConfirmationTimeout) { NSLog(@"_XCTSetEventConfirmationTimeout address found"); _XCTSetEventConfirmationTimeout(MY_NEW_EC_TIMEOUT); NSLog(@"_XCTSetEventConfirmationTimeout successfully called"); } else { NSLog(@"_XCTSetEventConfirmationTimeout address not found"); }
