Do you have to cook your game in order to test a WIP gauntlet test?

I’m trying to understand the Gauntlet Automation Framework, figure out how to create some tests and run them. However, every example I’ve seen so far seems to indicate that you have to cook and package the game before you can run a test

In order to run a gauntlet test, you have to use something like:

 [TABLE="border: 0, cellpadding: 0, cellspacing: 0"]
 	 		[TR="class: cke_show_border"]
 			RunUAT.bat BuildCookRun -project=<path_to_your_uproject_file> -platform=Win64 -configuration=Development -build -cook -pak -stage

This seems like a very slow workflow, and also hard to debug - is there any way to run a gauntlet test from inside the editor? Or what is the expected workflow when first creating a test?
