Automating Editor UI Tests

    TL;DR - Does Unity support or does Unity have plans to support Microsoft's UI Automation accessibility framework?

    I love writing Unity editor scripts, but find myself unable to test my editor UI in Unity's editor. A common approach is using computer vision to visually navigate UI tests, but many more experienced than myself will warn against this method. Using the Windows 10 SDK's Inspect.exe, it seems that Unity supports neither Microsoft's UI Automation nor the Microsoft Active Accessibility frameworks, blocking access to automate UI tests for engineers and screen readers for the disabled.

    How does the Unity QA team test editor UI internally and is there any good alternatives?

    As Unity's UI is not based on WPF, I doubt that they will be capable of supporting MS UI Automation. As I'm not really sure what blind users would do with the unity editor, I question the benefit of supporting it for that purpose.

    For functionality apart from the UI, Unity has built-in unit testing utilities. Their future plans to move over to a retained mode system for editor UI will eventually make it easier to separate functionality from the UI.

    If you have the patience and desire, you could probably write an autohotkey script to automate certain actions.

    In the meantime, the good old fashioned "click on everything" approach is your best bet.
