Scraping Pages for Resources

LoadForge supports using the HttpUserWithResources plugin for Locust, allowing you to automatically fetch all relevant page resources.

We typically advise creating your test to manually include resources you wish to fetch, as this will not execute JS, so you may want to fetch AJAX resources. Or alternatively, you could upload a browser recording (.har) to achieve that same.

Code

The below code requests the root of your website (/) and automatically also downloads anything matching this regular expression: .*[^(js|png|css|gif|woff)]$

In English, anything ending in .js, .png, .css, .gif, or .woff.

from locust_plugins.users import HttpUserWithResources
from locust import task


class TestUserWithResources(HttpUserWithResources):
    # these default values can be overridden
    # bundle_resource_stats=False
    # default_resource_filter=".*[^(js)]$"


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


    @task
    def include_resources_true(self):
        self.client.get("/", resource_filter=".*[^(js|png|css|gif|woff)]$")


    @task
    def include_resources_false(self):
        self.client.get("/dashboard", include_resources=False)
