Python Load Test Tool locust

Locust is an open source load testing tool. Use Python code to define user behavior, or to simulate millions of users.

Locust is a very simple to use, distributed, User load testing tool. Locust is primarily a load test for websites or other systems that can test how many users a system can handle concurrently.

The Locust is completely time-based, so a single machine supports thousands of concurrent users. Compared to many other event-driven applications, Locust does not use callbacks, but uses lightweight processing gevent.

Characteristics

• Write user test scenarios using pure Python code ; UIs or XML is not required

• Distributed & Scalable-supports thousands of users

• Web-based UI

• can test any system , although Locust is Web-oriented, but can also test any other system
