I've donwloaded JMeter 3.1 and am trying to run a junit sampler.
Per these instructions
jmeter.apache.org/usermanual/junitsampler_tutorial.pdf
I've added a ThreadGroup to test plan, i select add->sampler, but do not find Junit.
This is what I see. What am I missing?
no jmeter on menu
Here is an example photo I found on the tutorial.
enter image description here
I do have a junit class in a jar in the lib/junit folder.
This is weird, my JMeter 3.1 (installation comes with the JUnit Request sampler out of the box.
So please double check the following:
jmeter.log file - normally it contains enough information to guess the problem cause
you should have ApacheJMeter_junit.jar file under "lib/ext" folder of your JMeter installation. If it is not there - most probably something went wrong and your installation is corrupt
Be aware that you can add JUnit support (as well as any other JMeter Plugin) using JMeter Plugins Manager
For JMeter 5.0, the JUnit sampler did not appear for me when I incorrectly placed all my JUnit dependency jars in JMeter's lib/junit. It looks like it got stuck parsing all those jars looking for tests.
After placing JUnit dependency jars in JMeter lib folder and only the unit test jar in lib/junit, it worked correctly and JMeter GUI also started a lot faster.
I do have a junit class in a jar in the lib/junit folder.
This may be the problem in you case, if JMeter does not find any tests (or fails to find in my case), the JUnit sampler is simply not added to the UI

I want to write jmeter response to a excel file at particular cell.
I have kept tika jar in jmeter lib/ext folder but when I open Jmeter I get below errors
Please let me know how can I overcome this error or are there any other apache POI libraries which I can use?
Thanks
EDIT: I have freshly installed the Jmeter and that error is no more now thanks #Dmitri. I'm using "tika-app-2.6.0.jar" at lib folder I have below code in my beanshell sampler
but I'm getting below error when trying to run
Can someone help?
Thanks
It looks like a Jar Hell, i.e. you have several instances of Apache POI libraries in your JMeter Classpath and the Java Classloader picks the wrong .jar combination.
Also "lib/ext" folder is for JMeter Plugins, all the dependency .jar files should go to "lib" folder.
And last but not the least according to JMeter Best Practices you should always be using the latest version of JMeter so consider
Performing clean installation of JMeter 5.5 (or whatever is the latest stable JMeter version which is available at JMeter Downloads page)
Make sure that only one instance of Apache POI library is in JMeter Classpath ("lib" folder of your JMeter installation)
Restart JMeter to pick up the POI .jar(s). You can also use tika-app.jar but in that case make sure not to add anything else as Tika has POI bundled.
The error should go away
i try to select class file in jmeter junit request sampler.i want help how to choose my class file in junit request sampler
i export the package and stored it in apache lib->junit folder
then,restart the jmeter, but my class file is not visible in junit request sampler and i import all the selenium jar files into the project including selenium standalone jar.
#Test
public void performence()
{
WebDriver driver=new HtmlUnitDriver();
driver.get("https://www.spicejet.com/");
System.out.println( driver.getTitle());
}
}
please help me to resolve this
I think your main issue is probably you didn't put dependencies (Webdriver) of your JUnit classes in lib folder.
Check jmeter.log to see what the error is and clarify your question.
Try checking Search for JUnit 4 annotations (instead of JUnit3) box (it is not checked by default hence JMeter is looking for JUnit3-style annotations)
Make sure your class has an empty constructor or constructor with a single String parameter. Other class types are not supported as of JMeter 5.0
Make sure to place the .jar with your test into lib/junit folder of your JMeter installation and other libraries (i.e. Selenium java client) to lib folder of your JMeter installation. Carefully select dependency libraries versions in order to avoid so called JAR Hell as JMeter and Selenium might rely on different versions of the same library.
JMeter restart will be required to pick up any changes
Check jmeter.log file for any suspicious entries. In the absolute majority of cases JMeter will print the information regarding the error or failure there.
See How to Use JUnit With JMeter article for more information on JUnit and JMeter integration.
If you don't have large number of JUnit-based tests which you want to import into JMeter and you're starting development from scratch it might be easier to go for WebDriver Sampler plugin which provides JMeter with smooth Selenium support and possibility to write Selenium-related code in variety of languages including Java.
You can install WebDriver Sampler plugin using JMeter Plugins Manager
I have successfully exported JAR file from Eclipse to JMETER_HOME/lib/junit but when I try to import it in JUnit sampler of JMeter. It doesn't shows in
It does, however there are few things you need to remember:
You need to restart JMeter to pick the jar with your JUnit tests up
If your .jar file has dependency jars you need to put them somewhere into JMeter Classpath as well. Again, JMeter restart will be required so JMeter could read the .jar(s)
In the JUnit Request Sampler itself you need to tick Search for JUnit 4 annotations (instead of JUnit 3) box
Check jmeter.log file in case of any unexpected behaviour, it usually contains enough information to troubleshoot the issue.
Detailed information on JUnit and JMeter integration is available in the How to Use JUnit With JMeter article.
I've implemented a testing unit using spring (mock mvc), and I'm looking for a tool to run this unit in many threads/processes (so it will act as load testing for my server). I've seen applications like the grinder and jmeter but I don't want to re-write the entire unit, but just to use the existing one. Any ideas?
JMeter is able to execute existing JUnit tests via JUnit Request sampler, all you need to do is to drop jar(s) with your test along with dependencies somewhere in JMeter classpath and restart JMeter. Once done you'll be able to see your classes and methods in JUnit Request sampler dropdown and execute them in multithreaded manner.
See How to Use JUnit With JMeter guide for more detailed instructions and explanations.
I have set of functional tests written in Selenium and Cucumber-JVM, I use maven to run them by Cucumber tags.
Now I need to use some of those tests with JMeter to check performance. How can I do it?
I believe that you can just
Compile your tests into .jar file(s)
Copy the .jar file(s) into JMeter classpath
tests files - under /lib/junit folder of your JMeter installation
dependency files - under /lib folder
Add JUnit Request Sampler and choose required test from "Classname" and "Test Method" dropdowns
Configure JMeter as per your load scenario and run the test
See How to Use JUnit With JMeter guide for details on working with JUnit tests from JMeter perspective.
You can use JMeter sampler called BSF Sampler. This one allows to execute java class from JMeter. Please choose beanshell in the scripting language field.
