locust

A simple open source load testing tool that allows to define user behavior.

In order to set it up for the first time, we followed the documentation at https://locust.io/. In particular, we:

• Defined a class for the users that will be simulating.
• Defined a wait_time variable that will make the simulated users wait between the specified seconds after each task executed.
• Decorated our method with @Task that creates a micro-thread that calls this method.
• Defined the self.client attribute that makes it possible to make HTTP calls that will be logged by Locust.

To use, open the terminal on this folder and run the following command:

locust -f locust.py --host https://cara.web.cern.ch

Then, open up a browser and point it to http://localhost:8089. By default we pointed out the test to our own web server. Start swarming will trigger the simulation.
