Locust

Locust is an easy-to-use, scriptable, and scalable performance testing tool. You define the behavior of your users in regular Python code.

When to Use

• Python Teams: Scripting complexity is zero if you know Python.
• Distributed Testing: Easy to scale out using a Master/Worker architecture to simulate millions of users.
• Web UI: Comes with a nice web interface to start tests and view graphs in real-time.

Quick Start

from locust import HttpUser, task, between

class WebsiteUser(HttpUser):
    wait_time = between(1, 5)
