A set of useful plugins/extensions for Locust

Locust Plugins

The purpose of this project is to gather a curated set of plugins/extensions for Locust.

Locust itself is a "bare bones" load generation tool (compared to for example JMeter or Gatling) and it is left to the user to build even basic functionality (like reading test data from a database, limiting the request rate to a certain value, etc). Forcing everyone to reinvent the wheel is a big waste, and makes using Locust harder than it needs to be.

So I decided to publish my own plugins and hope that others (maybe you?) will contribute their solutions to common Locust use cases.

Having this separate from "Locust core" allows the plugins to evolve faster (at the expense of being less mature), and avoids bloating Locust with functionality you might not be interested in.

The plugins are grouped by type:

• listeners (request logging & graphing)
• locusts (new protocols like websockets & selenium/webdriver)
• readers (ways to get test data into your tests)
• tasksets (support for RPS limiting, and maybe other task sets in the future)
• utils (other stuff, like VS Code debugging support)

You can also have a look at the example locustfiles to learn how to use the plugins.

These plugins work well together with locust-swarm

Installation

pip install locust-plugins

Configuration

Configuration is mostly done through environment variables. You will get an exception if one is missing, and they should either be self-explanatory, or explained in the code where they are used. I recommend setting them permanently in your bash profile, so you dont have to set them every time or make your command line super-long.

Contributions

Contributions are very welcome! 😁
