Automatically validating Actors or Assets

Unreal provides a number of facilities for validating assets:

C++ only:

• CheckForErrors, used to validate actors placed in levels, but not actor assets.
• IsDataValid, which seems to mostly be intended for validating Data Assets

C++ or Blueprints:

• Editor Validators, which can be used to validate Blueprints and other assets, such as Automatically validating Actor Assets using Editor Validators

There are also a number of test automation tools.
