Gatling Testing

Introduction

Gatling testing is mainly used for load and performance testing, as it allows to inject users that would use the application at the same time in a real life environment.

Getting started

If you want to perform any Gatling testing in our application, you need to follow the following steps.

Recording

1. Download the tools of Gatling from their official page here
2. You need to be running your project, for that, see the readme file.
3. Open your browser -> Configuration -> Advanced configuration -> Proxy Settings -> LAN Configuration(In case of chrome) -> Advanced Settings -> Http: 127.0.0.1 Port: 8000 -> Save and apply
4. Now you will go to where your gatling files are located and open the Gatling recorder in the /bin folder, in case of windows the .bat file, in case of Linux or Mac, the .sh file.
5. Make sure you are listening to port 8000.
6. Set your outgoing proxy to the ip provided in the quickstart terminal of docker. Set also HTTP and HTTPS to 8082.
7. Now you can start recording!

Graphs and statistics

First of all remove the proxy that you set in the browser in the Recording part.

1. Once you have recorded something, go to your /bin folder and execute gatling.bat
2. If everything is right, it will show you some options, click enter and choose the one you want.
3. Go to the direction that the command line will suggest to you once it is finished to see the graphs and statistics.
4. Enjoy!

NOTE: You can modify the .scala files to add more users at the same time, in the last lines where it says

setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
