無法在iOS設備上運行XCTests

Question

我最近注意到我無法在iOS設備上運行測試。我已經試過兩個的iPhone 5和iPhone 6都失敗，這樣的錯誤：

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: 
    /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests: mmap() error 1 at address=0x0042C000, size=0x00099000 segment=__TEXT in Segment::map() mapping /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests 
DevToolsBundleInjection: Error loading bundle '/private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest' 

其他所有的測試錯誤，我在這個格式，網上能找到的是代碼簽名錯誤。這似乎並非是這裏的情況...

與這樣的其他錯誤，測試等待一兩分鐘，然後失敗，這樣的轉儲：

任何想法，爲什麼這可能會發生？

Answer 1

所以......儘管我相信相反，這是一個代碼簽名問題。在Xcode上手動設置測試目標（不是產品目標）的配置文件已通過設備啓動並運行。

與iOS模擬器相比，測試失敗的方式出乎意料（與信號量有關），但這是一個完全不同的討論。

希望這有助於某人。
