Jenkins as service user on OSX running IOS Simulator - ios

We are running Jenkins on an OSX server as a service user. The Jenkins user is restricted (not able to log in) because the server is accessible to the outside world.
We are running unit tests in the IOS Simulator. However, the simulator will start, but not run the app. I believe this is because Jenkins' user does not have UI access/permissions because we can run the app when logged in with users directly on the machine with UI.
Is there a way to add permissions to Jenkins user that will allow the IOS Simulator to run with UI without compromising security?

Are you running Jenkins as a daemon service? If so, it won't be able to interact with UI, see launchd man page
I ran into the same problem before when trying to perform UI Automation, so I configured Jenkins as launch agent of a user, then I could run UI test from Jenkins as that user.
For security, maybe you can setup access control on Jenkins see Standard Security Setup

Unable to open GUI Application through Jenkins

I'm new to Jenkins, I've created a Jenkins freestyle job used necessary plugins to invoke desktop application. When I execute the job with user credentials, I cannot see the application but application got up and logged on with user credentials. I'm doing GUI Automation which causes failures all the times when I try to run the job.
I created a batch file on HOST, calling the batch file through Jenkins. I have tried injecting the environment for job. I have enabled interactive services and Jenkins-slave on HOST machine. I tried to change NT/System user to Specific user. I enabled interactive services in both conditions. I'm not sure what I'm missing here. Do I need to install anything else, so far I have Jenkins-slave.exe on my HOST, I managed to generate executable Jar file using that.
Any help on this will be appreciated.
I'm calling the batch file, Jenkins cannot find the application opening apparently, it returning error as None type Object(Python) as described in screenshot.errors on Jenkins Job execution
I had a similar issue when I was trying to run Selenium UI Test on Windows Slave.
When the Slave is connected to Windows as a Service, then it does not bring up the application in foreground. It runs only in background even if you enable the service to interact with the desktop.
I had to change my browser to headless browser and then my test cases were passed in background mode.
My Old Question

jenkins slave runs as user

I have a jenkins setup with multiple users which are logging in with Active Directory plugin. This is useful so that each user can access his own tasks.
However each user also has different permissions on the local network, such as access to different folders etc. I have noticed that the permissions given to each task is not linked to the user but to the account under which the slave is running as service. Is there a way to change that so that the task is executed on the slave under the credential (and hence permissions) of the user?
Thank you
The problem is: there is only one slave process running the different job assigned to that server by the Jenkins master.
So the slave itself runs as one user (generally, a dedicated account or a system account).
Since you can get the user id as environment variable (with a plugin like JENKINS Build User Vars Plugin), you might consider configuring the job in order for it build step to "run as" the user who triggered the build.
See for instance the JENKINS Authorize Project plugin.
However, as mentioned this answer:
The "Authorize Project" plugin does not change the OS level user that is running commands.
It only sets the Jenkins user that is running the job and any downstream jobs, using Jenkins authentication (whatever it might be).
So you are left with build step with runas or su -c commands in order to be sure that your task does run with the right user.
I had the similar issue and I can recall for managing more control on projects I used role strategy plugin and setup global security using LDAP servers (Active directory should also be ok).
And I used authorized project plugin.
Have a look and I hope it should solve your purpose. Let me know on comment section for any clarification.
you can partially fix your problem this way:
install the slave as a service using the Java Web Start method and JLNP
go to Services control panel in windows
under Properties -> Connection replace the local system connection with a specific user
rebooted the service
This at least gives you the ability to use one account instead of system.

Webdriver with Jenkins

Selenium test (testNg) with mvn test from jenkins ,
I cant view the action performed on the browser, it is possible to view the real browser opened and performing action?
I suggest using SeleniumGrid.
You can then let the test run on a node, where you can see all the browser actions. For demonstration purposes, distributed and independent testing I did similar with teamcity for a regression-test project.
Basically there are two steps to setup the environment:
Start the grid for example as background-service.
Start a node which is running within a logged on user context (also as Service or autorun)
optional: Start another node for running tests in background
In your tests the creation of the the WebDriver instance changes like this:
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);
Here a link for more details to setup the Grid2: https://github.com/SeleniumHQ/selenium/wiki/Grid2
No. In typical setup, tests from Jenkins run on randomly available node. You don't know which node is available at a given point. Also typically Jenkins nodes tend to run headless browsers (like phantomjs) since they don't have displays.
Jenkins tests are meant to be run without any manual intervention, like on nightly basis for example. You develop tests locally, see how they run in a real browser and then push it to your main suite so that Jenkins can run it for you. If you want to run tests from Jenkins and view test running live then look for paid solutions like saucelabs or browserstack.
You can using BrowserStack. We have recently released a Plugin that allows you to view your test results right inside Jenkins. It's a paid tool of course :(
In Windows you should not install jenkins as windows application (because in this recent version, Microsoft decided to give services their own hidden desktop even you enable the functionality "interact with desktop" in jenkins service), you may have to deploy it from a war file as follows:
1) Download jenkins.war from Jenkins official site
2) Deploy it by the command prompt : java -jar {directoryOfJenkinsFile}/jenkins.war
3) Now you can access jenkins administration on http:// localhost:8080
Hope that helps you !

How to run jenkins job as a system user?

Rightnow, my jenkins jobs are run by Tomcat Server user.
I wanted it to run as User 'Admin', so i tried creating a slave and
added my same jenkins machine as the slave.
I have also added this as a windows service, and have confiured the
Admin user/pwd in the Logon Tab.
But still, when i run a job which executes the UI tests, i'm not able
to see them running in the firefox but it runs and the screenshots
are captured!
Are you asking how to have Jenkins spawn a process in your session that you can see at the monitor?
Have a look here: Open Excel on Jenkins CI, replace excel with whatever you are launching.
If you use jenkins as windows service, it won't allow GUI execution.
It only allows backgound running jobs.
If you want run UI test then stop your jenkins service , use some other way to connect your slave.

How can I get Xcode 5 to run iOS unit tests on a Jenkins slave?

We've been using Jenkins with the Xcode plugin to run continuous integration of our iOS applications including automatic execution and reporting of the unit tests. This worked well using Jenkins on a Linux machine and a Mac slave running Xcode 4.6.3.
Now we are looking to update the setup to Xcode 5 to support targetting iOS 7 and have run into the following problems.
First, the unit tests would not run at all because we were using the RunUnitTests script from Xcode 4 that is no longer supported in Xcode 5. I addressed this, as recommended by Xcode, by setting up the workspace with an appropriate scheme with the unit test target.
I then configured the Xcode step of the Jenkins job with custom xcodebuild arguments set to test -destination platform=${DESTINATION_PLATFORM},name=${DESTINATION_NAME},OS=${DESTINATION_OS} to get it to run the unit tests.
If I run the xcodebuild command line that the Xcode plugin for Jenkins runs in Terminal on my own machine, the unit tests run, but when the Jenkins job runs, it either fails or hangs when trying to run the unit tests.
I suspect this is because with Xcode 5 and the test buildaction instead of RunUnitTests script, unit tests now run in the iOS Simulator which requires an interactive session, and the Jenkins slave process is being run over SSH from the Jenkins master (Linux). If I am logged into the slave machine with the account Jenkins uses for SSH, I can see that the iOS Simulator launches when the unit tests are supposed to run, but the tests don't appear to run and the job hangs. If I am not logged into the slave machine, the Jenkins job fails to run the unit tests.
Is there any way to get the iOS unit tests to run on a Jenkins slave over SSH, and if not, any suggestions on how to keep automating the execution of the unit tests when the project must be built with Xcode 5?
Based on coffeebreaks' answer, I've come up with a full solution.
First of all, the Mac slave cannot be launched with SSH and must be launched manually using an interactive session and then left logged in at all times. In my situation, the slave is actually headless, so this is a further complication.
Here are the steps I used to get this all operational.
Create a new slave node on the Jenkins master configured with a unique label (I chose "xcode-unittests") and launch method set to "Launch slave agents via Java Web Start).
Login via screen sharing (VNC) to the Mac slave and start the slave agent. In my case, I could not get the slave to launch from the browser, probably because my browser did not have the necessary Java plug-in for running applets. I therefore used the command line javaws http://{jenkins-host}/computer/{slave-name}/slave-agent.jnlp. To make this a bit more robust, I configured this command to automatically run every time I login to the machine interactively, under System Preferences, Users & Groups, Login Items.
Quit Screen Sharing without logging out of the Mac slave. This keeps the interactive session running the slave agent alive, even though nobody is actually using the machine.
In order for the unit tests to run without prompting a user, I also had to run sudo DevToolsSecurity -enable on the Mac slave. This allows Xcode to interact with the iOS Simulator without interactively asking for permission to do so each time.
If the slave machine is ever rebooted, someone must login to the Mac slave to get the slave agent to run again. For that reason, I also left my SSH-based slave active as well. I split my Jenkins jobs into separate jobs for building the apps and running the unit tests. The jobs for building the apps are configured to run on the SSH-based slave, and the jobs for running the unit tests are configured to run on the interactive slave node described above. That way, if the interactive slave goes down, only the unit tests are affected, not the product builds.
Try starting your jenkins slave from a standard terminal on your Mac slave, not from the master using SSH.
See GBegen and coffeebreaks' answers. When the Jenkins is secured, use the alternative command line to start it from a screen share/VNC terminal session is
java -jar slave.jar -jnlpUrl http://jenkins-master:port/computer/jenkins-slave/slave-agent.jnlp -secret XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
What #GBegen said is correct and I used to do that before as well - Run the simulator and exit VNC without logging out, but that was not reliable. What I do now is to have a script that actually launches the simulator if it is not running. With Xcode 5 that broke as well, but I fixed it by adding the jenkins user to the admin group.
