Automation System User Guide

A guide to using the Automation System for Running Tests.

Choose your operating system:





Session Frontend with the Automation tab in focus.

The Automation tab is part of the Session (Unreal) Frontend . It's located here because it enables you to run automation tests on any other devices that are connected to your machine or are on your local network.

There are two ways you can access the frontend suite:

  • Session Frontend - Opens the local Editor as an automation worker to run automation on external devices.

    • Navigate to Window > Developer Tools > Session Frontend

  • Unreal Frontend - Opens a standalone version of the Frontend that includes the Session Frontend, Device Manager, and Project Launcher.

    • Navigate to your [UE4 Root Directory] > Engine > Binaries > Win64 > UnrealFrontend.exe

Enabling Plugins

In the latest versions of Unreal Engine 4, all the Automation Tests have been moved from the Engine Content folder to their plugins that must be enabled before they will be visible in the Automation tab.



To enable the plugins, select Edit > Plugins > Testing .

Plugins Browser with Automation Tests

If you're using the standalone Unreal Frontend, all the automation tests will be available without any additional steps to enable it.

User Interface

When you open the Session Frontend, you'll have access to a few tabs, such as the Console, Automation, Screenshot Comparison, and Profiler. For all your automation testing needs, the Automation tab will house all of the functionality you need with some additional functionality falling under the Screenshot Comparison tab for rendering functionality comparison.

If you do not see anything listed in the Automation tab window, select an active session from the Session Browse on the left. For example, under This Application the machine named RDU-WD is selected.

Session Browser

The Sessions Browser enables you to connect to specific instances of the Editor. You will only see the Automation window populate with the available automation tests once a session has been selected.



The toolbar in the Automation tab enables you to control how you start, refresh, and filter errors and warnings for your automation tests.

When your data is exported, a pop-up will indicate if it was successful and the save location of the CSV file.


The Export drop-down will only be active once reports have been generated, and the Export Data button will only become active if there are reports that meet the filter criteria.
