Xcode 6.0.1 fails to load test bundle for **iOS** application test target

[joshuatbrown]

I'm having what appears to be a similar issue as #565 - my test bundle doesn't load in Xcode 6. It's an iOS app that's been around for a while, and I'm using CocoaPods to pull Kiwi in. Here's my environment:

• Xcode 6.0.1
• Kiwi 2.3.0 (I've tried HEAD as well)
• CocoaPods
• iPhone 6 Simulator (iOS 8)

And here's the error message:

IDEBundleInjection.c: Error 3587 loading bundle '/Users/josh/Library/Developer/Xcode/DerivedData/MyApp-eqkdocnxomrmqdcpsvnruhralyhf/Build/Products/Test-iphonesimulator/MyAppTests.octest': The bundle “MyAppTests.octest” couldn’t be loaded because it is damaged or missing necessary resources.

I tried deleting Derived Data and testing in the iPhone 5s (7.0.3) simulator, but that didn't work either.

Same issue here...

[joshuatbrown]

I was able to work around this by doing the following:

1. Create a new iOS Application target - MyApp2, for example (this automatically creates a unit tests target)
2. Change the unit tests target to point to the main app target - MyApp, for example
3. Update the Podfile to include the following:

target :MyApp2Tests, :exclusive => true do
    pod 'Kiwi'
end

4. Run pod install
5. Add all the Kiwi specs to the new unit test target - MyApp2Tests
6. Update the MyApp scheme to use MyApp2Tests for testing instead of MyAppTests

I think that's all, but I'm probably forgetting something... If you see errors or have questions, feel free to post them here and I'll do my best to help.

Hmm ... I saw this a few times when working on Cedar, adding support for Xcode 6.

@joshuatbrown -- can you try changing the "Wrapper Extension" for your test bundle from octest to xctest?

Here's a screenshot of the setting in an example project I just created (down at the bottom):

My understanding is that prior to Xcode 6, the extension for test bundles was .octest and now it's .xctest and that Xcode will not load test bundles with the .octest extension.

@tjarratt this worked for me. thx!!!

[joshuatbrown]

@tjarratt I've already deleted my old test target in favor of my workaround from my previous comment, so I can't try that any more.

[tjarratt]

@joshuatbrown if you are using git (or some other version control) for your project then you could check out an earlier commit, before you deleted the test target and try that out.

Just a thought.

Hey everyone, is this still an issue? Would appreciate if someone could try on Kiwi 2.3.1 / Xcode 6.1 and let me know how it goes.

[tjarratt]

Hey @sharplet the interesting thing about this issue is that it should happen to anyone that takes an existing project (with Kiwi tests) from Xcode 5 and upgrades to Xcode 6. The extension for test bundles changed from .octest to .xctest and Xcode cowardly refuses to run the tests because it doesn't know how to use a test bundle with the older extension.

I'm not aware of any fix that Kiwi could apply to fix this, but would love to know if there was one. The problem, as I see it, is that the project build configuration needs to be changed (so that the test bundle's extension is updated for Xcode 6). Since the failure occurs when the test bundle is injected, I don't think there's any way at all for Kiwi to quickly go and fix it at runtime.

Is there a FAQ section for common problems when upgrading between Xcode versions? You might want to just document this as an Xcode defect.

@tjarratt Changing the wrapper extension to xctest worked perfectly. Thanks.

So, the reason it turned out it wasn't working is that the frameworks were not copied under build phase.

[sharplet]

@amol-c I have seen that issue before, but I think that's different to @joshuatbrown's original issue.

Speaking of which, is it still happening or did @tjarrat's fix work?

Hi,

I'm spending a lot of time looking for a workaround. I'm using an existing workspace and Cocoapods and now I'm adding the XCTest target, but when I ran this on iPhone6 simulator, it says

IDEBundleInjection.c: Error 3585 loading bundle 'PATH/TO/File.xctest': The bundle “TargetTest” couldn’t be loaded because it doesn’t contain a version for the current architecture.

While on other simulators (as iPhone4 and iPhone5 with different iOS version) it works fine.
Do you know something about this error? I also set Build Active Architecture Only to NO
