3.5.0 (2020.07.30)

  • New Feature

    • Introduce server mode agent
      • In previous version, nGrinder agents made TCP connections from agent to controller and this made hard to locate a nGrinder controller behind a firewall. From version 3.5.0, nGrinder introduces server mode agent so that a controller make a connection from a controller to agents.
      • See https://github.com/naver/ngrinder/wiki/server-mode-agent
    • Update agents automatically
      • When the test is executed with older version of agent, it triggers agent auto update.
    • Support GitHub script storage
    • Support MySQL
    • Improve test restart time
      • In previous version, nGrinder agent doesn't cache executed test lib & resources, Therefore, it took long time to execute tests in the case of using large amount of libraries and resource. From nGrinder 3.5.0, the test execution is much faster by sending only changed test resources to agents
    • Fade out nGrinder-recorder
      • nGrinder-recorder is no longer supported.
    • Support multiple user defined statistics
    • Ignore error count
      • Some of users want to continue testing even if there were many errors in the test. So nGrinder 3.5.0 supports that as a test option in advanced configuration panel
    • Support custom classpath

  • Modernize

    • Back-end
      • Spring boot
        • Change from spring framework 4 to spring boot 2.

3.4 (2016.05.24)

We have not been publically released nGrinder for last 2 years. It's true that we thought previous nGrinder was enough for our internal use. As time goes by, surrounding circumstances(for example Java version or Docker) was been changing.. So we decided to continuously enhance nGrinder.

  • New features and changes

    • Support Java 1.8
      • nGrinder now supports Java 1.8. Controller supports java 1.7 or above and Agent supports java 1.6 or above.
    • Provide elaborated script generator
      • Since nGrinder 3.0, we provided the script generation wizard that helps users easily create a default script.
      • However, it only created simple scripts for GET method case and people frequently asked to us how to use the other methods, how to use cookies and headers in the script.
      • In nGrinder 3.4, you can choose one of methods such as GET, POST and set HTTP headers and cookies in script creation form, then it will create useful example codes for you.
    • Provide a brand new nGrinder script recorder
      • A few years ago, we had released the script recorder based on JXBrowser. However it was not easy to run it due to several reasons.
      • Now, we have developed a brand-new script recorder from the scratch using the Chrome extension technology. If you are using Chrome browser, you can install nGrinder Script Recorder package.
    • Provide the dockerized nGrinder
    • Introduce new plugin architecture based on the PF4J
      • Previously we have used Atlassian Plugin Framework(APF) for plugins. However we found out it was too overwhelmed way to ngrinder extension and also found there are not much developers familiar with it.
      • So we dropped APF and adopt PF4J instead. See https://github.com/naver/ngrinder/wiki/How-to-develop-plugin for details.
    • Add intro.js for easy understanding.
      • You can find the very small button "Tip" on every pages. Click it and see what it is.

  • Bug Fix

    • #136 Support CJK for folder and script name
    • #111 GrinderUtils.getThreadUniqId() is not working in IntelliJ context

  • New feature and changes

    • One single executable package
      • Admins can run nGrinder controller using the following command. "java -XX:MaxPermGen:200m -jar ngrinder-controller-X.X.war"
      • nGrinder controller war file became the self-executable and Tomcat mount is supported as well.
      • Admins can download agents and monitors from the controller and users can download private agents and monitors from the controller.
      • The downloaded agent/monitor packages already contains the pre-defined configuration to connect the controller from which they are downloaded, so that no agent configuration is necessary.
      • See http://www.cubrid.org/wiki_ngrinder/entry/installation-guide
    • No more controller-agent connection problem
      • Previously nGrinder controller was bound to only one IP among all available IPs in the single machine. Sometimes this made it difficult to run nGrinder in which the internal and external IP are separated.(such as EC2)
      • Now nGrinder controller is bound to all available IPs in the OS to listen all connection requests such as agent connection, cluster member discovery, web connections so that the less connection error will be occurred.

3.2 (2013.05.10)

nGrinder is almost approaching to the ultimate performance testing solution. We believe nGrinder 3.2 is the most developer friendly performance testing tool ever.

  • New feature and change

    • We support not only Jython as a script language but also JUnit styled Groovy and Groovy Maven Project from 3.2.
    • We support more vusers per agent by calibrating agent's JVM options.
      • nGrinder 3.2 supports 4000 vuser(8 times more than before) per agent when you use Groovy and 4GRam agents.
      • Delete ${NGRINDER_HOME}/process_and_thread_policy.js to apply new process and thread policy in prior to ngrinder 3.2 installation.
    • Now agent machines are rarely crashed by memory swapping. nGrinder controller stops the test which uses more than 97% memory of agents by force.
    • IE10 is now partially supported. We added IE9 compatibility mode option to show nGrinder correctly in IE10. We will continue to completely fix this by 3.2.1
    • Graph fluctuation by nGrinder internal processing overhead is reduced. Now you can see the more stable graph.
    • The nGrinder usage is reported to our Google analytics everyday. We only collect the controller IP and the count of performance test run the last day.
      • If you don't like it, please turn it off by setting usage.report=false in system.conf
    • A user can run agents with the more detailed memory options
      • by providing grinder.memory.permsize=Value and grinder.memory.maxpermsize=Value in the unit of mega in grinder.properties file as same folder of the selected script.
    • SVN user can enjoy the user switching feature as well just like you do in the browser.
    • And.. several minor UI enhancements.
