JMeter with Jenkins: Performance Testing in CI Environment

Integrating JMeter with Jenkins has various advantages. It runs performance tests automatically for every new build. It also generates various performance metrics which can be used to track performance trend over time. And it is relatively simple to integrate JMeter with Jenkins, as we will see in this tutorial.
We will have Jenkins build trigger a Maven file, which in turn will trigger our performance test. At the end of a test, relevant performance metrics can be derived from generated report. Now, let’s start configuring our setup without further ado.

JMeter with Jenkins Setup:

  • Start Jenkins.
  • Navigate to Manage Jenkins–>Manage Plugins page.
  • Select Available tab and search for ‘Performance plugin’.
  • Install the plugin and restart Jenkins.
  • As we will be using GitHub for this setup, please install GitHub plugin as well.
  • Once plugin installation is done, we need to create a new Job in Jenkins. For that, go to Jenkins Dashboard and select New Item option.
  • Provide Item Name, select ‘Freestyle project’ and click OK.
  • Select Git under ‘Source Code Management’ section.
  • Provide ‘Repository URL’. For our GitHub repository, it’s https://github.com/TestingDiaries/maven-jmeter.git.
  • Under ‘Branches to build’ section–>Branch Specifier, add branch name for which you want to build.

  • Add a Maven build step with ‘verify’ as Goal.Maven Build Step
  • Now, select ‘Add post-build action’–>’Publish Performance test result report’ option.
  • Under ‘Performance report’ drop down box, select ‘JMeter’ option.
  • Provide ‘**/*.jtl’ as ‘Report files’. This sets up all the .jtl files as reports.
  • Check ‘Archive the artifacts’ check box and provide ‘**/*jtl-report.html’ value as ‘Files to archive’.

Jenkins Performance Settings

  • Click Save.
  • Record your JMeter script and save it in your Maven project’s src/test/jmeter directory.
  • Click Build Now. Once the build is run, you can see various performance reports in Jenkins.

JMeter Exceeded Maximum Number of Redirects Error Solution

While running performance test, JMeter allows maximum 5 redirects by default. However, if your system demands more than 5 redirects, it may result in JMeter exceeded maximum number of redirects error. In this post, we have listed down steps to overcome this error. Actual error in JMeter: Response code: “Non HTTP response code: java.io.IOException” Response message: “Non HTTP response message: Exceeded maximum number of redirects: 5” This error is noticed because  JMeter  allows maximum 5 redirects by default and your system may be using more than 5 redirects. You need to increase this count to more than 5 in jmeter.properties file. Follow below steps to achieve this. Navigate to /bin directory of your JMeter installation. Locate jmeter.properties file and open it in any editor. Search for “httpsampler.max_redirects” property in opened file. Uncomment the above property by removing # before it. Change to value to more than 5 Eg. 20. Save the file and restart JMet...

Performance Testing in the Cloud with JMeter & AWS

JMeter is a wonderful tool  to stress test your website and  your application architecture , however if you are trying to simulate many users (>1000) one JMeter instance (=pc) will not be sufficient. You will have to set up a JMeter cluster with multiple machines. JMeter is capable or running  distributed tests , but it comes with limitations. Since most of us don’t have multiple servers laying around somewhere, we usually go to cloud service providers like  AWS , spin up a couple of  EC2 instances  and turn them off whenever we’re done. Here is the problem, JMeter uses  Java RMI (Remote Method Invocation)  to communicate to its slaves, but these connections require all machines to be on the same subnet and this is not feasible with EC2 instances. Below, I explain how to get around this problem using a 3 node configuration in AWS to execute tests. I assume that you have a written the test already and have the .jmx file r...

Difference Between Redirect Automatically and Follow Redirects in JMeter

In this post, we will highlight important difference between Redirect Automatically and Follow Redirects options. These options are found in HTTP Request sampler of JMeter. Knowing the difference will help you decide your performance test strategy. When you check Redirect Automatically option, JMeter will not consider redirect as separate HTTP request. This in turn may result as lower response time in your overall performance test. Whereas Follow Redirect option will consider each redirection as separate requests. This may result in comparatively higher response time. This only has any effect if “Redirect Automatically” is not enabled. To see the difference between these two, record a sample script and run it by checking Redirect Automatically and Follow Redirects option. The second option will generate more requests in your result listener. As you can see from the above post, knowing the difference between Redirect Automatically and Follow Redirects option makes difference i...
