WordPress Load Test Example

Overview

Performance is crucial for ensuring a good user experience, and slow load times can negatively affect your website's SEO and user retention. By load testing (or stress testing), you can identify bottlenecks, server issues, or inefficiencies in your website code or configuration.

LoadForge offers an easy way to do this, and the best part? You can start with a free account!

Key Features of this Load Test

• Automatic Crawling: Once set up, the test will automatically crawl valid URLs from your WordPress blog or CMS. This mimics the behavior of real users who might hop from one blog post to another.

• Random Browsing: The test doesn't just stick to one URL. It picks links at random, offering a more realistic simulation of user behavior.

• Adaptability: While this guide uses the example of a WordPress blog, the principles can be applied to many types of websites and web applications.

Code Example

The provided code below is designed to:

• Request the /blog/ page of your WordPress site.
• Extract all the URLs from the anchor tags present on that page (i.e., your latest blog posts).
• Simulate users browsing those URLs at random.

Moreover, it simulates users accessing certain static contents like images, styles, and scripts which are essential for proper page rendering.

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

class QuickstartUser(HttpUser):
    wait_time = between(5, 9)

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

        link_elements = pq(".blog-list-post h2 a")
        self.blog_urls = []

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

    def on_start(self):
        self.index_page()

    @task(1)
    def static_content(self):
        # Fetch images
        self.client.get("/img/logo/logo.png")
        self.client.get("/img/images/cta_img.png")
        self.client.get("/img/images/footer_fire.png")
        # Fetch styles
        self.client.get("/css/compiled.css?id=629e6d86d0748098936a")
        # Fetch scripts
        self.client.get("/js/compiled.js?id=1a927dbcfa8d96520959")

    @task(3)
    def blog_post(self):
        url = random.choice(self.blog_urls)
        r = self.client.get(url)

    @task(3)
    def home_page(self):
        self.client.get("/blog/")

Tip: Make sure to adjust the static content URLs and the selector used to fetch blog URLs based on your site's structure and design. This ensures the test's accuracy and relevance to your specific WordPress setup.
