Locust: Open Source Load and Performance Testing Tool
Locust is an open source load and performance testing tool written in Python, simulating large numbers of concurrent users for web application testing.
What is Locust?
Locust is an open source load testing and performance testing tool written in Python. It is designed to test the performance of web applications by simulating a large number of concurrent users making requests.
Some key features of Locust:
- Simulates thousands of concurrent users making requests to target web apps
- Can generate various user behaviors through its Python API
- Has a web UI for visualizing response times, requests per second, and other metrics
- Lightweight, distributed, and scalable architecture using Python
- Easy installation through pip and runs on any system with Python installed
- Open source and has an active community behind it
- Integrates well with tools like JMeter, Gatling, Grafana, and more
Locust allows developers and testers to identify bottlenecks in their web apps before they go into production. By load testing early, teams can build more resilient services at scale. It is often used together with continuous integration pipelines.
