My apologies I was wrong about the -execcmd being able to easily run all of the complex tests for an automation test. 
You’ll wan to run with: -automationtests=“Blueprints.Compile-On-Load”
The couple of issue with that is the editor/game will exit once the automation test que is empty which is fine if that is what you want it to do. This also may or may not run all of the available complex tests.
I’ve logged these issues into our database to hopefully make this easier to use.
To get a full name of a complex test you can run the editor or game with -Execcmds=“Automation List” or in the editors console window entering Automation List. That will give you the full list.
