Yes Cheat Codes, They are Actually Helpful in Testing the Game we Need Them!!! So Larian Please Let us know what the Cheat Codes are ( God Mode, Unlimited Gold, Stats ect....) Or Someone Knows Please Post on This Thread.
You would need to sign into a formal NDA with Larian in order to have the use of one of their builds with all of the extra testing tools, unfortunately.
Outside of official channels, you could use mods that shortcut a lot of those little things, but doing so is always going to throw of the overall value to the test data you get.
Choose your stats mod on nexus. Choose stats, AC, movement, actions, summon heaps of magic items, adds feats, adds some weapon/ armor proficiencies....
