I am executing the Jmeter test plan on Ubuntu Server but at the end left with an error saying:

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/opt/testScripts/LcLoadTesting/agentsAccessTheCustomerInfo.jmx'. Cause: CannotResolveClassException: com.googlecode.jmeter.plugins.webdriver.sampler.WebDriverSampler

The whole error is:

It seems that you're using the WebDriver Sampler in your Test Plan and your JMeter installation on Ubuntu doesn't have this plugin installed.

The solution is to install the plugin, it can be done using JMeter Plugins Manager

  1. Get the Plugins Manager:

    wget https://jmeter-plugins.org/get/ -O /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar

  2. Get JMeter Plugins Command Line Runner:

    wget https://repo1.maven.org/maven2/kg/apc/cmdrunner/2.2/cmdrunner-2.2.jar -P /opt/apache-jmeter-5.2.1/lib/

  3. Generate Plugins Manager command line utility:

    java -cp /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar org.jmeterplugins.repository.PluginManagerCMDInstaller

  4. Install the WebDriver Sampler plugin:

    /opt/apache-jmeter-5.2.1/bin/./PluginsManagerCMD.sh install jpgc-webdriver

Replace /opt/apache-jmeter-5.2.1 with the full path to your JMeter installation and your test should work after executing of the above 4 commands.

  • First two steps go fine but in the third one I got an error saying: Error: Could not find or load main class org.jmeterplugins.repository.PluginManagerCMDInstaller Caused by: java.lang.ClassNotFoundException: org.jmeterplugins.repository.PluginManagerCMDInstaller What can I do in this case to resolve this.

  • Most probably you made a mistake or typo somewhere, I cannot state where exactly without seeing all the commands output

  • By seeing your answer I got an idea and place the needed jars in respective folders of JMeter i.e. /lib/ext. And now the test plan executed but not in a way that it should be. I have print the logs for more information and I got one error from chrome driver i.e. java.lang.IllegalStateException: The driver is not executable: /opt/chromeDriver/chromedriver at com.google.common.base.Preconditions.checkState(Preconditions.java:585) ~[guava-25.0-jre.jar:?]. Can you tell me this why it's not working? If you want a seprate question for this then I will post it accordingly within a minute ??

    You need to make it executable using chmod command like chmod +x /opt/chromeDriver/chromedriver. And looking into my magic ball I can predict that the next question will be "my browser doesn't start" so get familiarized with Driving Headless Browser Testing with Selenium and Python article

    If you want to automate Chrome browser you need to have it installed, don't you? wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb and sudo apt install ./google-chrome-stable_current_amd64.deb should do the trick for you. See Using Selenium with JMeter's WebDriver Sampler for more details
