How do I tell Jenkins what to run on my slave machine? - jenkins

My Jenkins master is up and running. I have created a slave node, launched it successfully from the slave machine, and have done the web services installation so that the connection is established on startup of the slave machine. I have also created a "job" that builds successfully in Jenkins.
How do I tell Jenkins what to actually do on my slave machine? I want to use Jenkins to run an IntelliJ test suite (Selenium and Cucumber) on the slave machine, but haven't been able to figure out exactly how to get it to do this. Note: I've just started looking into the Seleniumhq plug-in, but I'm not sure if this is what I need or not since I'm working with a remote slave.

Limit where the jobs can run using the 'Restrict where this project can be run' to your slave node.
Distributed Builds in Jenkins

My confusion here stemmed from not having my project connected to a VCS repository. Without it, I couldn't figure out how to build-out my project's workspace in the slave environment from Jenkins. I also didn't understand the concept of adding additional build steps at the time I asked this question.
Once I had the VCS connection set-up (I had to do some finagling with Git/Visual Studio Team Services to get it connected, which is why I went with "none" as my version control option at first), my workspace was built for me on the slave machine when I built the project from Jenkins. Then, I used a combination of build steps ("execute Windows batch command" and "Invoke top-level Maven targets") to carry-out the rest of the project's functions.

Jenkins: how to run an exe on a remote computer

I just started using Jenkins. Still not familiar with all its features.
I would like to run a Ranorex test which is on a remote computer. How can I do that from Jenkins?
To execute binaries on a specific host, you can use slaves.
Here is a guide to setup master and slave on windows:f
https://wiki.jenkins-ci.org/display/JENKINS/Step+by+step+guide+to+set+up+master+and+slave+machines+on+Windows
You will run the slave on the remote computer and connect it to the master.
To run the slave on your remote computer, you have to download the slave.jar and start it on the remote computer. This is described in the wiki article above.
You have to ensure, that your job is executed on the slave. This can be done by labels. You configure a label on the slave and configure the same label on the job too.

Running HP Load Runeer or QTP from Jenkins

I have HP Load Runner installed in Windows 2012 and its hosted in the cloud.
For running load runner scripts, I connect to the system via mstcs, open the Virtual User Generator application and run the scripts.
Now I want to run the scripts via Jenkins( installed in a different system ) and I tried using the Jenkins HP Application Automation Tools plugin but I was unable to figure out how to do that.
In Jenkins I found out the following option:
Execute HP functional tests from HP ALM
Execute HP tests from file system
Execute HP tests using HP ALM Lab Management
Execute HP tests using HP Performance Center
But I am not sure how to use them or any of these will work. Can some please help me with this?
For individual scripts alone, mdrv command line. For controller alone wlrun command line. You may refer to knowledge base articles on the arguments to employ.
Have you gone through the documentation for HP automation plugin for Jenkins?
At last I figured out how to integrate it.
Integrating HP Load Runner:
For Running HP Load Runner scrips there is a Jenkins plugin named HP Application Automation Tools.
The challenge for us was the fact that Jenkins and Load Runner were installed on separate machines. We had Jenkins installed in our Dev server and HP Load Runner installed on cloud. If both were installed on the same machine then the task would be as simple as providing the filesystem path for Load Runner Scenario *.lrs files, in Execute HP tests from file system plugin.
So I went ahead and installed a slave instance of Jenkins in our CTC in which Load Runner was installed.
Steps to setup Jenkins slave instance.
On your master machine go to Manage Jenkins -> Manage Nodes.
New Node --> Enter Node Name.
Select Dumb Slave --> Press OK.
Fill out the following:
Set a number of executors (one or more) as needed.
Set a Remote FS Root, a home directory for the master on the slave machine. For a Windows slave, use something like: "C:\Jenkins\"
Set a label so that you can use that label to run jobs on the slave machine.
Select the appropriate Usage setting.
Launch Method: An easy way to control a Windows slave is by using Launch slave agents via Java Web Start (Recommended for Windows).
Availability --> Keep this slave online as much as possible
Press OK.
Now you need to connect your slave machine to the master using the following steps.
Open a browser on the slave machine and go to the Jenkins master server url (http: //your jenkins master:8080/).
Go to Manage Jenkins > Manage Nodes, Click on the newly created slave machine. You will need to login as someone that has the "Connect" Slave permission if you have configured global security.
Click on the Launch button to launch agent from browser on slave.
Run the program.
Now you should see the Slave machine connected under Nodes.
If you want the service to run on start-up of the slave machine do the following (Windows only directions):
In the Slave agent program running on your slave machine, click File --> Install as Windows Service.
Start, type Services and Select the Services program.
Find Jenkins Slave in the list, Double click to open.
Select Startup type --> Automatic.
Go to the Log On tab, change the Log on as to a user of your choice (Special user account Jenkins recommended).
Make sure that auto login is set for the slave machine for the user account, then the VM (or physical computer) should connect and be available when needed.
Creating Load Runner job in Jenkins:
Create a new freestyle project in Jenkins.
Check the "Restrict where this project can be run" checkbox and choose the Label Expression what you have provided for Slave Jenkins.
Under Add build step select Execute HP tests from file system and inside the Tests textarea provide the path of the folder of cloud machine which is having your Load Runner Scenario *.lrs scripts .
Click on build, Jenkins will trigger the Jenkins slave instance in cloud machine which will in turn invoke the Load Runner Controller and run the controller scripts(*.lrs).
Integrating HP QTP Scripts:
Steps for integrating HP QTP Scripts are exactly same as for HP Load Runner, the only difference is :
HP Unified Functional Testing should be installed in the same machine where you are going to configure Jenkins as a slave instance.
Under Add build step select Execute HP tests from file system and inside the Tests textarea provide the path of the folder of CTC machine which is having your HP QTP scripts .
Running Windows Server 2012 R2 Datacenter in a VM & want it set up as a jenkins node to run HP ALM test sets. In step 6, setting jenkins slave to run as a service, I received 'access denied' from jenkins slave agent process. Open a cmd prompt as admin user, cd to the jenkins slave install directory and enter
jenkins-slave.exe install
to fix this. Next, run services, locate the jenkins slave service. Should say 'Automatic', so 'start' it up and trial run your jenkins job. Check by rebooting the new jenkins slave platform and checking the service comes back as 'Automatic'.

Is there a stable plugin for Jenkins for running builds on VMs?

Travis CI has a really nice feature, builds are run within VirtualBox VMs. Each time a build is started, the box is refreshed from a snapshot and the code copied on to it. Any problems with the build cannot affect the host, and you can use any OS to run your builds on.
This would be really good, for example, compiling and testing code on a guest OS that matches your production env. Also, you can keep your host free of any installation dependencies you might need (e.g. a database server) and run ITs without worrying about things like port conflicts.
Does such a thing exist for Jenkins?
Check out the Vagrant Plugin https://wiki.jenkins-ci.org/display/JENKINS/Vagrant-plugin
This plugin allows booting of Vagrant virtual machines, provisioning them and also executing scripts inside of them
You can run Jenkins in a Master Slave Setup. Your Master instance manages all the jobs but lets all the slaves do the actual work. These Slaves can be VMs or physical machines. Go To Manage Jenkins -> Manage Nodes -> New Node to add Nodes to your Jenkins Setup.
There is the vSphere Cloud Plugin and the Scripted Cloud Plugin that can be used for this purpose.

Defining executables for a slave on Jenkins

I am very new to CI systems like Jenkins.
I have a master Jenkins server running on Ubuntu. I have one Ubuntu slave (managed over SSH) ,which is dedicated to Android builds, having Android SDK and others already available.
My question is how I can tell the Jenkins master the path of android SDK on the slave server?
Go to Manage Jenkins -> Manage Nodes, and open configuration page for the slave node. Add environment variables, which will then be given only to that slave.
If you define environment variables which are used by default by the SDK, then this is enough. Otherwise you will also have to edit the job to use these (I mean, like in execute shell script build steps).
I'm not familiar with the Andriod SDK specifically, but could you pass it as a parameter to the build?

How to setup my remote slave with Jenkins?

In therory Master is : Job and Slave is : Node (however that what im understand).
I installed JENKINS in 2 machines MAC OS X (maybe windows whatever), I set up my job with a correct repository and configure xCode in this job etc ... like same tutorial, i set up my slave etc ... all fine and 10/10 BUTTT this test is local test, in one machine.
My problem is : I want have SLave(Node) for building my xCode Project in MAC OS, and My Matser (job) in others server (why not my seconde machine MAC OS X), How i can establish connection between slave (Node) and Master(job) for building my project xCode in my Remote SLave.
Set your job to use "Restrict where this project can be run" by checking the box and put the name of the slave in the box (use quotes if there are spaces
I had a little trouble deciphering your questions so if this does not answer please rework what you are asking.
Easy set the IP address of the slave host machine in the Jenkins setup. Choose ssh as the communications method and set up accounting information on the slave machines jenkins setup. Make sure the slave machine can ssh to the account and machine you set up in jenkins. Your ready to roll
How to link jobs in Jenkins
Master job: "Trigger/call builds on other projects"
Slave job: Add a Condition Step build: "Run? Build Cause --> UpstreamCause (with The master project name)" and then copy the artifacts (.) from the "Master" job.
Don't forget to copy from the workspace and not from the latest successful build, since the master didn't finished yet and din't publish the artifacts.
