Checking Status Codes

Overview

Below is a snippet that allows you to test, for example, that the webserver actually returns a 404 not found. It can be useful to look for specific status codes that you want in replies.

You can apply this to various use cases such as expecting a specific 4xx or 2xx reply from certain content types. If the response below was not a 404 you would see an error reported in your LoadForge report.

Code

import time
from locust import HttpUser, task, between

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

    @task(1)
    def index_page(self):
        self.client.get("/")
    
        with self.client.get("/does_not_exist/", catch_response=True) as response:
            if response.status_code == 404:
                response.success()
