Loadmill offers two solutions that can be evaluated separately during a proof of concept (POC): Droid for mobile testing and the classic Loadmill platform for end-to-end web and API testing. Choose the section that matches the solution you want to evaluate—you do not need to complete both setup processes.
Droid has a lightweight POC setup and can be evaluated independently from the classic Loadmill platform.
- A mobile app that you can use for testing.
- A Mac or Windows computer capable of running the Droid CUA desktop app.
- A reliable internet connection. Droid connects to Loadmill's cloud services during the POC.
Once these requirements are in place, follow the Droid CUA Getting Started guide to install the desktop app and prepare your first test.
Use this setup to evaluate the classic Loadmill workflow for creating and running end-to-end web and API tests.
In this step, we will test the Algorithm component. Open your web application in Google Chrome.
Press F12 (or right-click → Inspect) to open the Developer Tools, then navigate to the Network tab.
Ensure the record button (●) is active.
Perform the use case manually, step by step.
Once complete, right-click anywhere in the Network tab and select “Save all as HAR with content.”
Email the saved .har file to us along with the corresponding manual test case.
If you’re unable to email the HAR file, please create a user account at https://app.loadmill.com/app/signup and share the file through the chat box.
If your test environment is not publicly accessible, please whitelist the following Loadmill IP addresses for the POC:
- 52.42.51.230
- 54.190.108.53
- 193.189.107.30
Loadmill requires two agents to be installed for the POC:
Used for test creation on web applications.
If you are unable to install the extension from the browser store, manually install it using the link below:
- Open Microsoft Edge and click the three dots (⋯) in the top-right corner.
- Go to Extensions → Manage Extensions.
- Enable Developer Mode (toggle on the left).
- Click Load unpacked and select the extracted folder from the ZIP file.
- The Loadmill Composer extension will now appear in Edge.
To begin recording:
- Open your target website (e.g., BUPA).
- Right-click anywhere → Inspect.
- In the Developer Tools, click the “+” icon, find Loadmill Composer, and drag it to the left pane.
- You can now start recording user steps directly in Loadmill Composer.
The Desktop Agent acts as a Test Runner for web applications and also supports test creation for mobile and desktop applications.
