What is Locust?
Locust is an easy-to-use, distributed, user load testing tool. It allows you to define user behavior in Python code, making it flexible and powerful.

Prerequisites
  • Python installed on your machine (Python 3.6+)
  • Basic knowledge of Python

Step 1: Install Locust
First, install Locust using pip:
  
pip install locust

Step 2: Create a Locustfile
Create a new Python file called
locustfile.py. This file will define the behavior of your simulated users.

Step 3: Define User Behavior
In locustfile.py, import necessary modules and create a user class. Here's a simple example:

from locust import HttpUser, task, between

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

    @task
    def my_task(self):
        self.client.get("/")

Step 4: Run Locust
To start Locust, run the following command in your terminal:
locust -f locustfile.py

Step 5: Access the Locust Web Interface
Open a web browser and go to
http://localhost:8089
. You'll see the Locust web interface where you can configure and start your load tests.

Step 6: Configure and Start the Test
  • Number of users to simulate: Enter the number of concurrent users.
  • Spawn rate: Enter how many users per second to start.
  • Host: Enter the URL of the application you want to test.


Here Are more advanced Scripts:

1- POST request to a login page
from locust import HttpUser, task, between

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

    @task
    def index(self):
        self.client.get("/")

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

2-Use User-Agents
from locust import HttpUser, TaskSet, task, between
import random

class UserBehavior(TaskSet):
    USER_AGENTS = [
