I am trying to figure a way to add my Jenkins job parameters displayed in job configure page into slave node (windows PC).
So meanwhile if anyone know How to add Jenkins job parameters into system variable of a windows PC.
Please do share it.
Consider the following use case:
You set up a test job on Jenkins, and it accepts a distribution bundle
as a parameter and perform tests against it. You want to have
developers do local builds and let them submit builds for test
execution
on Jenkins. In such a case, your parameter is a zip file that contains
a distribution.
Your test suite takes so much time to run that in normal execution you
can't afford to run the entire test cycle. So you want to control the
portion of the test to be executed. In such a case, your parameter is
perhaps a string token that indicates that test suite to be run. The
parameters are available as environment variables. So e.g. a shell
($FOO, %FOO%) or Ant ( ${env.FOO} ) can access these values.
Example:
my.prop=${env.BAR}

I set up a Jenkins to integrate the JMeter script. Using the Freestyle project in Jenkins, I enabled "This project is parameterized" to set a String parameters for the Threads, Loop_Count and Think Time.
In .jmx file, I used the Function Parameters function to define those
variables, as shown below image:
User Defined Variable
In Jenkins, I configured the parameterization as shown below:
Set Parameterization
Command Line
However, when running the test for 40 users using the Build parameter in Jenkins, it looks like the # of threads/users are not correct that is being executed, the Samples that are being generated only 3 for most of the pages. Only the Homepage (which is the first page on the test) is only getting the correct # of Samples, but the rest of the URLS/pages are not correct. Below the actual output.
Output
Can you please help what might the causing this issue, I already checked the Jmeter script and jenkins config and appears to be correct but still I'm getting the issue. Thanks for the help.
Setting parameters in Jenkins itself is not sufficient to pass them to JMeter, you need to pass this parameterized value to JMeter startup script via -J command-line argument
-Jusers=%users%
End-to-end demo:
More information: Apache JMeter Properties Customization Guide
The Setup - A jenkins job using jenkins parameters testApp and testEnv. The Execution Batch looks like this:
C:\jmeter\apache-jmeter-3.2\bin\jmeter.bat -n -t
C:\JMeter\Scripts\API_scripts\%testApp%.jmx -Jtestenv=%testEnv% -JtestApp=%testApp% -JtestBrowser=NA -l
C:\AUTO_Results\jtl\%testApp%_%testEnv%.jtl
Post-build Actions
Console output (build lob) parsing with a global rule so that the Failures that are logged in the Jenkins Console window will consider the JMeter script failing. (discussed Jenkins shows JMeter script failure even though the script actually passed)
Triggered parameterized build - this is a separate jmeter script that updates a wiki page with either PASS/FAIL and uploads the JMeter report.
The Issue - How do I get the downstream Triggered build to use the parameters from the upstream script? I set the Parameter = Current build parameters but it's not applying those. Also, I wont know the value of the testResult parameter until the upstream build finishes. I tried adding %testResult%=PASS to the 'Predefined parameters' box
As per Parameterized Trigger Plugin page:
The parameters section can contain a combination of one or more of the following:
a set of predefined properties
properties from a properties file read from the workspace of the triggering build
the parameters of the current build
Subversion revision: makes sure the triggered projects are built with the same revision(s) of the triggering build. You still have to make sure those projects are actually configured to checkout the right Subversion URLs.
Restrict matrix execution to a subset: allows you to specify the same combination filter expression as you use in the matrix project configuration and further restricts the subset of the downstream matrix builds to be run.
So you basically need to copy over the parameters you would like to have in the "downstream" job from the current one.
As a workaround to current performance plugin limitations you can consider running JMeter using Taurus tool as a wrapper, it has flexible and powerful pass/fail criteria subsystem which will basically return to Jenkins non-zero exit code triggering build failure in case of issue in the test. If everything goes well Taurus exit code will be 0 which is considered successful by Jenkins. Check out How to Run Taurus with the Jenkins Performance Plugin article for more details.
Say I've got dev, qa, and stable server environments for some web app, with corresponding git branches. Each environment should be continuously integrated. Each of these environments has a separate username/password pair used to publish the app. I would like to make a Jenkins multiconfiguration (matrix) job to publish to all of these environments. The publishing almost certainly must be done with a shell script.
My failed attempt consisted of using the Jenkins Credentials and Credentials Binding plugins. Credentials Binding provides a way to inject credentials as environment variables using a parameter. However, setting this parameter dynamically (i.e., something like if ENV == dev: CREDS = CREDS_dev) doesn't appear to be possible. Build scripts happen afterwards, and even using the Environment Script plugin doesn't work.
Is there any way for this to happen?
Had similar situation and used groovy script with parameterized build (https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin). In my case I had a choice parameter defined as "DEPLOY" and had different values, like "Test", "Release", then in the following groovy script (Evaluated Groovy script):
if ("Test".equals(DEPLOY)) {def map = [DEPLOY_URL: "http://someurl", DEPLOY_STORAGE: "testaccount"]; return map }
You should be able to specify your credentials in here or copy env variables. After that you can access these variables in windows batch command using:
echo %DEPLOY_URL%
echo %DEPLOY_STORAGE%
I also had another choice parameter defined "Deploy.Branch", with values of "dev" and "master". And used it as a parameter to Branches to Build, the value was set to (if you want to dynamically specify branch based on parameters):
*/${Deploy.Branch}
Hope this helps.
Here's what I ended up doing. It's kind of a workaround for what I would argue is a flawed design or missing use case in Jenkins.
Redid my creds so they have standard IDs (this is in the Advanced part and you can't set it after creation)
Matrix job runs a trivial script to figure out what env maps to what creds ID, then triggers...
The main job that does the deployment
I have a jenkins job that runs some tests and promotes the build if all tests pass.
I then have a second job that has a 'Promoted build parameter' which is used for deployments.
THe idea is that the deply job should let you pick one of the prompted builds for deploying. The issue I'm having is that I can pick a promoted build, but I have not idea how I access information about the build.
I've named the build parameter
SELECTED_BUILD
And according to the docs this should then be available via the environment.
The problem is that it doesn't seem to be bound to anything.
If I run a build step to exectute this sheel script:
echo $SELECTED_BUILD
echo ${SELECTED_BUILD}
The values are not interpolated / set.
Any idea how I can access the values of this param?
Many Thanks,
Vackar
Inject the information as variable user jenkins plugin (eject evn variable).
while triggering parameterized build on other job, pass above variable as parameter to next job.
choice parameter
Name
a
b
c
I have a parametrized build with choice parameters like a,b,c,d. When I select a parameter, it has to do fresh checkout, and, when I select b it has to update the work space of Jenkins.
Right now whatever the parameter choose either a,b,c, it is checkout policy is fresh checkout only.
Can any one let me know how to set different properties based on the selected parameter.
You would have to forego the Jenkins SCM checkout configuration, and maintain the SCM checkout through a script (either Execute Shell or Execute Batch Command). Your script would then handle the logic of doing a certain type of checkout/update based on passed parameters
Late edit:
You could configure a Pre-scm Build Step, and there run either a Conditional Build Step or a plain shell execution (bash or batch). In that shell, test the param, and if it matched b, then wipe the local workspace/checkout folder from the shell script.
When the rest of the job runs, it will do a fresh checkout (since the workspace/checkout is empty). With other param options, it will run the job normally, doing an update.
I haven't tried this. Your biggest issue may be if pre-scm build step does not have access to environment variables at that time.
