What you’ll learn

Gatling Fundamentals for Stress Testing APIs – Java – 2022

  • Setup, installation, and configuration of the Java version of Gatling from scratch, with no prior knowledge required.

  • Using the Gatling Recorder to convert your API transactions from Swagger, Postman, or cURL into a Gatling script

  • Learn the layout template of a Gatling script and what to add to each section

  • Explore and write core Gatling script functionality such as adding loops, refactoring code to objects, adding test data through feeders, and much more

  • Create realistic load test scenarios in your Gatling script, and learn how to execute them from the command line

  • Use the Maven build tool to execute Gatling scripts, and observe your stress test execution in real-time through the command line in Gatling

  • Analyze the test reports generated by Gatling’s built-in reporting tools


  • Some basic experience in any computer programming language will be helpful, but not required

  • Experience in using Java is a plus, although again not required to follow along with the course

  • Previous experience with any performance testing tool will be a small help, but again not in any way required


Gatling has been around since 2012 and has since grown into a hugely popular open-source tool for stress testing any web application or API. Until recently, Gatling had only been available in Scala, which has hindered many users from adopting the tool.

In 2022, Gatling finally released a


version of the tool, eliminating the need to use Scala and opening the doors for widespread adoption.

In this course, you will learn the fundamentals of using the


version of the


stress testing tool. We will write many Gatling scripts from scratch against a target application created specifically for this course.

Why Gatling?:

  • Extremely




    performance and stress testing solution
  • An


    tool, so no cost to use it

  • Performance testers with Gatling experience are in high demand

    yet few Engineers know how to use this tool

Why this course?:

  • Learn all aspects of the Java version of Gatling including:

    • Installation & Configuration, both standalone and in an IDE using the


      build tool
    • Using the Recorder to record your user journey, both with




    • Writing many Gatling load test scripts from scratch, learning all fundamental concepts
    • Analyzing test results reports
  • See how to write many scripts from scratch to become familiar with the process, each script teaches a new concept
  • Run tests from the command line using the Maven build tool.
  • Although Gatling scripts are pure Java code, you will see why the excellent Gatling DSL means no real knowledge of Java  is required to succeed with Gatling
  • Resources for learning Gatling are scarce. It can be overwhelming and intimidating trying to learn this tool on your own from scratch. This course is designed to address that

What are the benefits of taking this course?:

  • Have fun whilst learning a valuable skill & tool
  • Command a higher salary
  • Improve your skills and offer as a developer and tester

This course is for any



Quality Engineer

that wants to learn how to use the Java version of


for adding

performance and stress tests

to their test suite.

No prior knowledge of performance testing or software development is required

, as I will be walking you through the entire process. However, any prior knowledge or experience that you do have in these domains will be of benefit and will naturally aid learning.

If you want to add an awesome, fully open-source performance testing tool that is in high demand across a wide range of software development roles to your skillset, this is the course for you.

Who this course is for:

  • QA Engineers and Programmers with little or no experience with Gatling
  • Anyone using an alternative load testing tool like JMeter, LoadRunner, or NeoLoad that wants to learn a new tool
  • Developers looking to add a powerful, fun, and an intuitive new tool to their knowledge-base
