无法在iOS设备上运行XCTests

我最近注意到，我无法在我的iOS设备上运行testing。 我已经尝试了iPhone 5和iPhone 6.都失败了，像这样的错误：

2015-07-13 12:32:26.930 MyApp[1316:735999] Error loading /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests: dlopen(/private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests, 262): no suitable image found.

我在网上发现的所有其他testing错误都是代码签名错误。 这似乎并不是这种情况

与其他这样的错误一样，testing等待一两分钟，然后失败，如下所示：

任何想法，为什么这可能会发生？

Answer 1

所以…尽pipe我相信相反，这是一个代码签名问题。 在Xcode上手动设置configuration文件到testing目标（而不是产品目标），让我的testing通过设备运行。

与iOS模拟器相比，testing失败了一种新的和意想不到的（与信号量有关的）方式，但是这是一个完全不同的讨论。

希望这有助于某人。
