What Will I Learn?

• Installation and configuration of Gatling from scratch, with no prior knowledge required
• Using the Gatling Recorder to model the behaviour of your existing application directly into a Gatling script
• Setup your development environment for writing your own Gatling load test scripts
• Learn the layout template of a Gatling script and what to add into 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
• Design load test scenarios in your Gatling script, and learn how to execute them from the command line
• Use build tools like Maven to execute Gatling scripts, and watch your performance test execution in real-time through the command line in Gatling
• Access and analyse the test reports generated by Gatling’s built in reporting tools

Requirements

• Some basic experience in any computer programming language will be helpful
• Experience with Scala is a plus, although not required
• Previous experience of any performance testing tool will be a help, but again not required

Target audience

• 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
