无法在 iOS 设备上运行 XCTests

Question

我最近注意到我无法运行在我的 iOS 设备上进行测试。我已经尝试了 iPhone 5 和 iPhone 6。两者都失败并出现如下错误：

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.  Did find:

DevToolsBundleInjection: Error loading bundle '/private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest'

我在网上发现的所有其他这种格式的测试错误都是代码签名错误。这里似乎不是这种情况...

与类似的其他错误一样，测试会等待一两分钟，然后失败并出现如下转储：

知道为什么会发生这种情况吗？

Answer 1

所以...尽管我不这么认为，但这是一个代码签名问题。在 Xcode 中的 test 目标（不是产品目标）上手动设置配置文件使我的测试顺利进行并运行通过了设备。

与 iOS 模拟器相比，测试以一种新的和意想不到的（与信号量相关的）方式失败，但这是一个完全不同的讨论。

希望这对某人有所帮助。
