I have a XCTest bundle which I can run through xcode on a simulator by using simctl. I am using the iPhone 6 iOS 9.1 simulator with the following environment variables:
export SIMCTL_CHILD_TestBundleLocation="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator/Tests.xctest"
export SIMCTL_CHILD_XCInjectBundle="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator/Tests.xctest"
export SIMCTL_CHILD_XCInjectBundleInto="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator/ios_app.app/ios_app"
export SIMCTL_CHILD_XCTestConfigurationFilePath="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator/Tests.xctest/Tests-7025D700-AA6C-4343-9C7A-92F9CC3A1C42.xctestconfiguration"
export SIMCTL_CHILD_DYLD_LIBRARY_PATH="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Frameworks"
export SIMCTL_CHILD_DYLD_FRAMEWORK_PATH="/Users/User/ios_app/DerivedData/primus/Build/Products/Debug-iphonesimulator:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Frameworks"
The app is already installed on the simulator by this point and the simulator is running and I run:
xcrun simctl launch booted uk.co.company.ios.app -NSTreatUnknownArgumentsAsOpen NO -ApplePersistenceIgnoreState YES -XCTest All
The app launches and from the simulator log I can see that the XCTest bundle loads but the tests don't run. I have logged out where it seems to stop and there is a private method _checkForTestManager, more specifically _checkManagerForDaemonStateAndConnectIfAvailable. From what I can tell XCTest is trying to connect to testmanagerd but failing. So I tried kickstarting testmanagerd on the simulator using:
xcrun simctl spawn booted launchctl kickstart system/com.apple.testmanagerd
But this doesn't seem to have an effect on the tests running, but I do see some additional output in the simulator log:
testmanagerd[41610]: Received new test session connection (-[XCTestManager listener:shouldAcceptNewConnection:])
testmanagerd[41610]: Initial orientation 0
testmanagerd[41610]: Test session <__NSConcreteUUID 0x7fd2bb804a00> 7025D700-AA6C-4343-9C7A-92F9CC3A1C42 requested socket (-[XCTestSession _XCT_requestSocketForSessionIdentifier:reply:])

testmanagerd[41610]: -[XCTestManager _handleRequestForSessionWithIdentifier:]
But nothing after that. Compared with when running through Xcode:
testmanagerd[41309]: Test session <__NSConcreteUUID 0x7fd162b016a0> 64B7815C-A0A2-4213-9A5E-E0BB0139F35A requested socket (-[XCTestSession _XCT_requestSocketForSessionIdentifier:reply:])

Is it possible to run tests through simctl this way?
