我最近注意到，我无法在iOS设备上运行测试。我在iPhone 5和iPhone 6上都尝试过，但都失败，并显示如下错误：
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:

我在网上用这种格式发现的所有其他测试错误都是代码签名错误。这里似乎不是这种情况...
与其他类似错误一样，测试将等待一两分钟，然后失败，并出现以下转储：

任何想法为什么会发生这种情况？
最佳答案
所以...尽管我有相反的看法，但这是一个代码签名问题。在Xcode中手动在测试目标（而非产品目标）上设置配置文件，可以启动我的测试并在设备上运行。
与iOS模拟器相比，该测试以一种新的，出乎意料的方式（与信号量相关）失败了，但这是一个完全不同的讨论。
希望这对某人有帮助。
