Swarm Your Site with Locust

TLDR

Locust, a Python load-testing framework, can help you set up load-tests like a breeze.

Sets up complex UI interactions with ease
Supports Docker for simulating real-world load

How I Use It

For testing single engpoint request:

Gather stats of the sites' load distribution, i.e., Top Active Pages in Realtime, from Google Analytics
Based on the data, set up endpoints-of-interest and give each weight accordingly
Spin up Docker containers that matches the test criteria, i.e., 50 clients for C50
```
$ docker-compose up --scale worker=50
```
Use Locust's web UI to start the test

Example

load_test.py

import time
from locust import HttpUser, task, between
 
class SomeUser(HttpUser):
    wait_time = between(1, 2)
 
    #  268 is the weight of the endpoint
    @task(268)
    def index(self):
        self.client.get("/")
 
    @task(264)
    def posts(self):
        self.client.get("/posts")
 
    @task(147)
    def about(self):
        self.client.get("/about")

docker-compose.yml

version: '3'
 
services:
  master:
    image: locustio/locust
    ports:
      - '8089:8089'
    volumes:
      - $PWD:/app
    command: -f /app/load_test.py --master -H http://master:8089
 
  worker:
    image: locustio/locust
    volumes:
      - $PWD:/app
    command: -f /app/load_test.py --worker --master-host master
