无法在iOS设备上运行XCTests [英] Unable to run XCTests on iOS device
问题描述
我最近注意到我无法在iOS设备上运行测试。我试过iPhone 5和iPhone 6.两者都失败了，出现了这样的错误：
I've recently noticed that I can't run tests on my iOS devices. I've tried on both an iPhone 5 and an iPhone 6. Both fail with an error like this:
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:

我在网上发现的所有其他测试错误都是代码签名错误。这似乎不是这里的情况...
All the other test errors I've found on the net with this format are code signing errors. This doesn't appear to be the case here...
与其他类似的错误一样，测试等待一两分钟，然后失败转储如下：
As with the other errors like this, the test waits for a minute or two, and then fails with a dump like this:

任何想法可能会发生这种情况？
Any ideas why this might be happening?
推荐答案
所以...尽管我相信相反，但这是一个代码签名问题。在Xcode中的 test 目标（而不是产品目标）上手动设置配置文件，我的测试已经通过设备运行。
So... despite my belief to the contrary, this is a code-signing issue. Manually setting the provisioning profile on the test target (not the product target) in Xcode got my test up and running through the device.
与iOS模拟器相比，测试以新的和意外的（信号量相关的）方式失败，但这是一个完全不同的讨论。
The test fails in a new and unexpected (something semaphore-related) way compared to the iOS Simulator, but that's a whole different discussion.
希望这有助于某人。
