Multi-user Login Examples - LoadForge Docs

Overview

LoadForge allows you to login to any website, and then browse the site as a logged in user (or set of users).

We recommend learning about regular user logins before this guide.

LoadForge will automatically keep sessions, meaning you can login and then browse the site like a browser would.

This guide will give you an example of how to login as different users throughout the test, simulating multiple user logins and site usage. Note that this typically isn’t needed, as 1000 requests from a single login is generally the same load as 1000 separate users.

Generated users code example

from locust import HttpUser, TaskSet, task, between
import time

class AwesomeUser(HttpUser):
    wait_time = between(10, 20)

    # On start populate our user list
    def on_start(self):
        self.createUsernames()

    # Create an array of user1 -> user1000
    def createUsernames(self):
        self.users = []
        for i in range(1000):
            self.users.append("user"+str(i+1))

    # Fetch the next user in our list
    def getUsername(self):
        return self.users.pop()


    # Login to the site
    def login(self):
        username = self.getUsername()
        loginInformation = {
            "username": username,
            "password":"passw0rd"
        }

        self.client.post("/login", loginInformation)

    # Logout from the site
    def logout(self):
        self.client.get('/logout', name="logout")


    # Define our tasks here
    @task(1)
    def load_page(self):
        # Login first
        self.login()

        # Put your logged in tasks here
        self.client.get('/profile/info')

        # Logout now
        self.logout()

The above code creates 1000 users named “user1” through “user1000” and logs in with each of those. It’s designed for a 1000 user test of course. You can easily modify this. You can also pick usernames at random like so:

import random
def getUsername(self):
    return "user" + str(random.randint(1, 1000))

You can modify this test to suit whatever pre-populated user system you have. You could also consider registering users with the test and clearing your database afterwards.

LoadForge is powered by locust, meaning open source locust users can copy this script as well. If you are a locust user, consider importing your script to LoadForge to supercharge your testing!
