4 days ago - If you want your users to loop, perform some conditional behaviour or do some calculations, you just use the regular programming constructs provided by Python. Locust runs every user inside its own greenlet (a lightweight process/coroutine). This enables you to write your tests like normal (blocking) Python code instead of having to use callbacks or some other mechanism.

Below is a quick little example of a simple locustfile.py: · Here we define a number of Locust tasks, which are normal Python callables that take one argument (a Locust class instance). These tasks are gathered under a TaskSet class in the tasks attribute. Then we have a HttpLocust class which ...

October 4, 2016 - quickstart - The locust.io quickstart tutorial that logs in and load tests pages on a grafana installation

We’ve declared two tasks by decorating two methods with @task, one of which has been given a higher weight (3). When our QuickstartUser runs it’ll pick one of the declared tasks - in this case either hello_world or view_items - and execute it. Tasks are picked at random, but you can give them different weighting. The above configuration will make Locust three times more likely to pick view_items than hello_world.

Once you run this command, the test will start immediately, and start logging output. It should run for the duration you run the test, and hitting ctrl+c may orphan some locusts.

March 13, 2024 - This guide will help you to set up Locust in your local environment and create your very first basic load test. Practice your performance testing skills with Mad Devs.

April 3, 2025 - This guide will take you through the process of setting up and using Locust.io to test your website’s performance effectively.

The idea is that during a test, a large number of simulated users (“locusts”) will send requests to your website. The behavior of each user is defined by you and the overall process is monitored from a web UI in real-time.

November 7, 2024 - Load testing is here to save you! Here's a simple quick start guide to locust to get you started.
