我尝试在带有Xcodebuild的iphonesimulator上运行我的测试，但我总是遇到同样的错误。
我的命令行：
xcodebuild clean test -workspace App.xcworkspace -scheme "UI Tests" -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=9.2'
stacktrace：
xcodebuild[31826:741511] [MT] IDETestOperationsObserverDebug: (796137A0-CB6A-490D-BF89-767DF586BE26) Beginning test session 796137A0-CB6A-490D-BF89-767DF586BE26 with Xcode 7C68 on target <DVTiPhoneSimulator: 0x7fef34dce060> {

当我直接在Xcode上调用测试时，我有任何问题。
有什么想法吗？ 感谢您的帮助。
干杯。
