This section provides an overview of the locust_demo under the /performance-testing/ path. Locust is an open-source load testing tool that makes it easy to hit your app with many simulated users.

  • What is Locust?

    • Locust is a distributed, user-centric load testing tool. It allows you to simulate thousands of users hitting your system in a way that is similar to real users.

  • Why use Locust?

    • Simulate real user behavior.
    • Run tests on-premise or in the cloud.
    • Write tests in Python, which makes it easy to integrate with your existing codebase.

  • How to run a Locust test?

    • Install Locust: pip install locust
    • Create a locustfile.py with your test scenarios.
    • Run the test with locust --host=http://localhost:8089/

  • Example Test Scenario

    • This is a simple test scenario to simulate users logging in to a website.
from locust import HttpUser, task, between

class WebsiteUser(HttpUser):
    wait_time = between(1, 5)

    @task
    def login(self):
        self.client.post("/login", data={"username": "user", "password": "pass"})
