How to run ios simulator for ui Automation test on jenkins

Question

I'm trying to run a UI Automation script from jenkins :

instruments -w 'iPhone 6 (8.1 Simulator)' \
-t '/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.xrplugin/Contents/Resources/Automation.tracetemplate' \
'myAppName' \
-e UIASCRIPT 'some_path' \
-e UIARESULTSPATH 'some_other_path'

But I'm getting an error and the simulator won't start

Waiting for device to boot...
2015-03-18 10:29:04.064 instruments[13082:64124] [MT] iPhoneSimulator: Could not launch simulator: -10810

I does work when running from the command line under the jenkins user.

Any Help would be much appreciated, thanks.

It's probably related to the fact, that you're not running your Jenkins master or Jenkins slave in a desktop session, meaning that it does not have access to your GUI (e.g. it can't launch anything that pops-up a window or a dialog).

So you either need to start the Jenkins master manually or allow it to access the GUI if it's run as a service (not sure how to do this on Mac OS). Another way would be to run a Jenkins slave on the same machine, started via JNLP.

The following Stackoverflow issues deal with the same error message/code and suggest similar solutions:

• Timed out waiting 120 seconds for simulator to boot
• Launching XCode Simulator with jenkins user

You can use github.com/stisti/jenkins-app to run jenkins from Desktop session – Flight
