Load Testing with Locust#

Load test web applications with Locust: users and tasks, wait times, events, HTTP requests, response validation, step load and distributed mode.

How each session works#

  1. The big idea: the topic in plain words, with an everyday example.

  2. A picture: a diagram of the idea.

  3. Real runs: every test was run with Locust 2.28 against a small practice shop on your own computer, and the output you see is what it printed.

  4. Common mistakes: what trips beginners up.

  5. Hands-on exercises: try first, then open the solution.

  6. Practice: a quiz for the session.

Important

Only load test systems you own or have written permission to test. The practice shop in code/shop_server.py is yours to hammer. Numbers such as requests per second differ on every computer and every run; look at the shape of the results.
