Login Examples

Test that logs in and then requests a profile page.

You are now browsing the LoadForge locust test directory. You can use these tests as a starting point for your own tests, or use our AI wizard to generate one automatically.

Overview

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

This example test posts to a login page when it starts, then requests /profile and some static content normally. This is a great example for logging into a site and then requesting content after login.

The on_start definition will be run once by each individual simulated user. So they all login first, and then execute your various tests.

There are other useful guides for this topic:

Sessions are automatic

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

Basic code example

import time
from locust import HttpUser, task, between

class QuickstartUser(HttpUser):
    def on_start(self):
        # Form post to /login with email and password
        self.client.post("/login", {
            'email': 'user@domain.com',
            'password': 'passw0rd'
        })

    @task(2)
    def profiles(self):
        self.client.get("/profile")

    @task(1)
    def statics(self):
        self.client.get("/img/logo.png")
        self.client.get("/css/styles.css")
        self.client.get("/js/scripts.js")

Advanced code example

This test starts with a login and a request to the index page of the site. It then finds all anchor tags (a href) and randomly browses through them.

import random
from locust import HttpUser, TaskSet, task
from pyquery import PyQuery

class AwesomeUser(HttpUser):
    def login(l):
        l.client.post("/login", {
            "username":"EXAMPLE_USER",
            "password":"PASSWORD"
        })

    def index_page(self):
        r = self.client.get("/")
        pq = PyQuery(r.content)

        link_elements = pq("a")
        self.toc_urls = []

        for l in link_elements:
          if "href" in l.attrib:
            self.toc_urls.append(l.attrib["href"])

    def on_start(self):
        self.login()
        self.index_page()

    @task
    def load_page(self):
        url = random.choice(self.toc_urls)
        r = self.client.get(url)

Using basic authentication

You can easily login using basic auth with any LoadForge request by adding the auth parameter to your get or post request object. In this example below, we will try to login as user1 with password password1.

We have two examples below, one POST request with data and another GET request with just authentication.

import time
from locust import HttpUser, task, between

class QuickstartUser(HttpUser):
    wait_time = between(3, 5)

    @task
    def login_samples(self):
        self.client.get("/myUrl", auth=("user1", "password1"))

        self.client.post("/myUrl",
                         {"item": "123", "button": "submit"},
                         auth=("user1", "password1")
                     )

CSRF tokens

We have a full guide available on handling login pages that require CSRF. Please continue to Handling CSRF.


Locust Test Example

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!
