This document introduces Gatling, an open source load testing tool. It discusses some issues with traditional load testing approaches like limited scalability and usability. Gatling addresses these by using asynchronous processing without blocking I/O, supporting thousands of concurrent users on a single JVM. It provides both a graphical interface and a Scala DSL for defining test scenarios. Gatling also offers out-of-the-box support for common testing patterns and the ability to integrate with other tools for reporting.

- 1. How to stress test your application with Gatling ? Lausanne, September 13th 2012
- 2. Why a new tool ?
- 4. Issue n°1: High performance http://www.shopfbparts.com/catalog/nal-19201331_w.jpg
- 5. 1 user = 1 thread
- 6. With 50 threads on a JVM http://www.ausmotive.com/F1/2010/British-GP-05.jpg
- 7. With 2000 threads on a JVM
- 8. Blocking IO
- 9. That's what your threads will do most of the time, waiting ... http://www.flickr.com/photos/carlotancredi/3447589391
- 12. Graphical Interface Listen, it's actually not complicated ... http://www.spacebio.uni-bonn.de/ahp/Parabel/Par_Images/240304-Cockpit_BIG.jpg
- 14. What was this change about ?
- 15. Listen to us, Gatling can change all that ! http://static.lexpress.fr/medias/15/mai-68_124.jpg, copyright by AFP
- 16. Say hello to my little friend ...
- 17. Be asynchronous, embrace the actors model
- 18. Don't use blocking IO > Netty > Async-Http-Client
- 19. Scenario = Code = DSL http://gringocentralsanramon.blogspot.ch/2012/02/getting-published-writing-seminar-wed.html
- 20. version 1.3.0 Expected by the end of September 2012 All examples will be based on this version
- 21. Easy
- 23. Feeling lazy? Try the recorder.
- 25. Powerful : write your own Scala code
- 26. But, many used case covered out-of- the-box by the DSL ● .regex() / .css() / .xpath() / jsonPath() ● .find() / .findAll() / .count() ● .is() / .in() / .not / .whatever ● .doIf() / .repeat() / .during() / . asLongAs() ● .tryMax() / .exitBlockOnFail() ● .randomSwitch() / .roundRobinSwitch() ● .feeder() : csv() / tsv() / jdbc()
- 27. Polling
- 28. Markov chains (Cycles are not supported so far...)
- 29. See also : .roundRobinSwitch()
- 31. Coming soon : > Live reporting in Graphite > Jenkins reports > Clustering
- 32. Fact sheet ● First commit in june 2011 ● Created by S. Landelle and R. Sertelon ● About 20k LOCs ● 19 persons have contributed to the project ● 2000 downloads since the beginning ● 500 downloads of Gatling 1.2.5
