Define user behaviour with Python code, and swarm your system with millions of simultaneous users. Tweet Follow @locustio. No need for clunky UIs or bloated XML. Just plain code. Locust supports running load tests distributed over multiple machines, and can therefore be used to simulate millions of simultaneous users.
A Locust test is essentially just a Python program making requests to the system you want to test. This makes it very flexible and particularly good at implementing complex user flows. But it can do simple tests as well, so let’s start with that:
Locust is an open source performance/load testing tool for HTTP and other protocols. Its developer-friendly approach lets you define your tests in regular Python code. Locust tests can be run from command line or using its web-based UI.
While Locust itself is a pure Python package, it has some dependencies (e.g. gevent and geventhttpclient) that are compiled from C code. Pretty much all common platforms have binary packages on PyPi, but sometimes there is a new release that doesn’t, or you are running on some exotic platform.
