http://locust.io
What is Locust?
- An open source load testing tool
- Write test scenarios in python code
- Distributed, can simulate millions
of simultaneous users
What Locust provides
to the developer
- A framework for simulating user behaviour
- An HTTP client (python-requests)
- A web interface that show statistics
- Ability to run your code distributed
across multiple machines
from locust import HttpLocust, TaskSet, task
class UserBehaviour(TaskSet):
@task(30)
def index_page(self):
self.client.get("/")
@task(10)
def press_page(self):
self.client.get("/press")
class WebUser(HttpLocust):
task_set = UserBehaviour
min_wait = 5 * 1000
max_wait = 60 * 1000
$ locust -f locustfile.py --host http://instagram.com
Master -Slave Mode
