Quick Facts about JMeter

JMeter Crashes the Performance Party - 1998

Picture it: 1998, the aroma of Fresh Prince still lingers in the air, and bam! Apache JMeter struts onto the scene, crafted by Stefano Mazzocchi of the Apache Software Foundation. This nifty tool was concocted for the thrill of crushing load test problems - basically the party animal of performance testing!

Unleash the Scripts - The JMeter Revolution!

Fast forward, and JMeter pulls a rabbit out of its hat: it's no one-trick pony! This bad boy dances with Java to test performance like a boss, but get this—it's a script kiddie's paradise. With support for scripting languages like Groovy, you can whip up test scripts like you're a wizard at Hogwarts, minus the wand.

Meet JMeter's Cool Sibling - 5.4.1 Edition

And then along came JMeter 5.4.1, striding in like it owned the place in February 2021. Decked out with glitzy features like a JSON Path extractor and a shiny HTML reporting dashboard, it's like the Tesla of performance testing – high-tech, fancy, and everyone wants a ride!

Example code snippet of a basic JMeter test plan (just kidding, we’re keeping it high-level).

Top 10 JMeter Related Tech

1. 
   

   Java

   
   

   Java, this granddaddy of programming languages, isn't just for your grandpa's desktop app! It's the backbone of JMeter, so if you're skimping on your Java skills, you might as well be pouring your coffee down the drain. Brush up on loops, classes, and, of course, the million-and-one ways to handle exceptions without pulling your hair out.

   
   

   
         // A simple Java loop example
         for (int i = 0; i < 10; i++) {
             System.out.println("Java is essential for JMeter: " + i);
         }
       

   
   



2. 
   

   Apache Ant

   
   

   Crucial for JMeter, Apache Ant zips around like a colony of busy little digital insects, automating builds with the finesse of a maestro. You'll want to know your way around its XML build files unless you prefer doing things the hard way... manually, like a caveman etching a wheel for the first time.

   
   
   
   



3. 
   

   Bash Scripting

   
   

   If JMeter had a Swiss Army knife, Bash would be the little tool you forgot about but absolutely needed at a campsite. A tiny bit of Bash scripting goes a long way, as you'll often automate JMeter tests on servers where clicking isn't a thing. Join the cool kids: script your heart out! #NoMoreManualLabor

   
   

   
         #!/bin/bash
         # A simple Bash script to run JMeter tests
         JMeter -n -t my_test_plan.jmx -l test_results.jtl
       

   
   



4. 
   

   Jenkins

   
   

   Flaunt your JMeter tests with Jenkins in the DevOps fashion show. It's like putting your automated tests on a runway; Jenkins will tirelessly run them, display the trendy test results, and notify the squad if the build breaks down like a model tripping over high heels. Keep it continuous, keep it integrated, stay fabulous.

   
   

   
         pipeline {
           agent any
           stages {
             stage('JMeter') {
               steps {
                 sh 'JMeter -n -t performance_test.jmx -l results.jtl'
               }
             }
           }
         }

   Git is the time-traveling wizard of source control. Messed up? No problemo, just roll back the changes like they never happened. Collaborating with a team? Presto, you can work on your JMeter scripts in parallel universes and then merge them without casting any dark spells. Accio Git Skills!

   
   

   
         # Clone a repository with JMeter scripts
         git clone https://github.com/example/jmeter-tests.git
         
         # Checkout a new branch to work on a new test plan
         git checkout -b feature/new-test-plan
       

   
   



7. 
   

   Docker

   
   

   Pack your JMeter tests in containers and ship them across the seven seas of server land. Docker is like having a portable testing lab that you can replicate faster than rabbits in spring. Just make sure you understand the dark arts of Docker networks and volumes or things might get overboard!

   
   

   
         # Dockerfile snippet to run JMeter in a container
         FROM alpine
         RUN apk add --no-cache jmeter
         CMD ["JMeter", "-n", "-t", "/tests/my_test_plan.jmx", "-l", "/results/results.jtl"]
       

   
   



8. 
   

   Apache Groovy

   
   

   Fancy adding some extra oomph to your JMeter scripts? Apache Groovy is like your script's personal wizard, casting spells in the form of concise expressions and language-level integration with Java. It's so smooth and dynamic; you'll be weaving test magic with the flick of a wrist.

   
   

   
         // Groovy assertion example in a JMeter script
         vars.put("response", prev.getResponseDataAsString())
         if (!prev.isSuccessful()) {
           log.error("Oops! Request failed.")
         }
       

   
   



9. 
   

   Postman

   
   

   You might think, "Wait, isn't Postman just for RESTful siestas?" Sure, but JMeter and Postman can party together. Design and test your APIs with Postman and then export them to JMeter for that heavy-duty performance testing rave. It's like having a quiet dinner date before hitting the club!

   
   
   



10. 
    

    REST Assured

    
    

    When you've grown weary of JMeter's GUI and yearn to write your performance tests in the tranquility of your IDE, REST Assured is your hermit's retreat. Craft elegant API tests in Java like a barista brewing a delicate espresso. It's just Java, but REST Assured makes it look like poetry.

    
    

    
          // REST Assured simple get request
          given().when().get("https://api.example.com/data").then().assertThat().statusCode(200);
