Agent Testing Quick Guide

This quick guide shows how to get access to Loadmill Agent Testing, create a simple agent-based test, and run it against a real web UI from the desktop app.

---

Before you start

You will need:

• A Loadmill account

• A plan that supports AI Agent capabilities (if you have a promo code, you can use it during sign-up to activate access)

• The Loadmill desktop app installed

---

Step 1: Sign up and activate access

Create your account here: Sign up to Loadmill

If you already have a Loadmill account, you can skip the sign-up part of this step.

If you received a promo code by email, open Billing after signing in and apply the code there. This enables access to the Agent step for eligible accounts.

Open the Billing page from your account settings.

Step 2: Download the desktop app

Download the desktop app here: Loadmill desktop app

Important: The desktop app is required to run Agent steps.

If you already have the desktop app installed, you can skip this step.

Step 3: Create your first agentic test

1. Open the Loadmill desktop app and create a new test suite.

2. Add a new step and choose UI Agent.

Add a new UI Agent step

1. Enter a short prompt that describes the user flow you want the agent to perform on your site and what it should validate.

1. Run the test you created.

This is the fastest way to get started: give the agent a short, real UI task and validate that it can complete it reliably.

Keep the first run simple. Start with one short path on your site so you can watch how the agent navigates the UI and validate the result.
