What options do I have for Automation and Unit Testing In Unity?

A registry listing all of the prominent options for automating UI testing in Unity. Provides a high level comparison of what each package offers. People may not realize that there are now many choices to automate UI testing in Unity, along with additional alternative options for unit testing
Inside my company we have very similar in-house solutions. It takes time and expertise to create such infrastructure from scratch, so packages provided in the list may help to save some time if used correctly.

At Unity Labs we perform a great deal of experiments. These frequently produce 'gems' or small algorithms that are useful to the community by themselves. This is a repository of those gems.

Contains:
- Stabilizr : Object Stabilization for XR
- GizmoModule: Gizmos for EditorXR/Runtime
- PhysicsTracker: Bridging the gap between game code and physics simulation
- RunInEditHelper: Manage what is running in edit mode
- ModificationResponse
- MissingReferences: Track down references to missing assets or methods
and many more.
