    Locust

    Build Status codecov license PyPI PyPI GitHub contributors

    Locust is an easy to use, scriptable and scalable performance testing tool. You define the behaviour of your users in regular Python code, instead of using a clunky UI or domain specific language. This makes Locust infinitely expandable and very developer friendly.

    Features

    Write user test scenarios in plain old Python

    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. Because your scenarios are “just python” you can use your regular IDE, and version control your tests as regular code (as opposed to some other tools that use XML or binary formats)

    from locust import HttpUser, task, between
    
    class QuickstartUser(HttpUser):
        wait_time = between(1, 2)
    
        def on_start(self):
            self.client.post("/login", json={"username":"foo", "password":"bar"})
    
        @task
        def hello_world(self):
            self.client.get("/hello")
            self.client.get("/world")
    
        @task(3)
        def view_item(self):
            for item_id in range(10):
                self.client.get(f"/item?id={item_id}", name="/item")

    Distributed & Scalable - supports hundreds of thousands of users

    Locust makes it easy to run load tests distributed over multiple machines. It is event-based (using gevent), which makes it possible for a single process to handle many thousands concurrent users. While there may be other tools that are capable of doing more requests per second on a given hardware, the low overhead of each Locust user makes it very suitable for testing highly concurrent workloads.

    Web-based UI

    Locust has a user friendly web interface that shows the progress of your test in real-time. You can even change the load while the test is running. It can also be run without the UI, making it easy to use for CI/CD testing.

    Can test any system

    Even though Locust primarily works with web sites/services, it can be used to test almost any system or protocol. Just write a client for what you want to test, or explore some created by the community.

    Hackable

    Locust is small and very flexible and we intend to keep it that way. If you want to send reporting data to that database & graphing system you like, wrap calls to a REST API to handle the particulars of your system or run a totally custom load pattern, there is nothing stopping you!
