How do you test your squad formations?

This comes up a lot, I am sure. But what methods do you use to test out the strength of your squads?

Winter Storm

This is a popular one. You join WS and go around attacking people using the squad to get the battle reports. Then you can plop your base next to the drop boxes and have them attack you to get some good defense battle reports.

Explorer Truck

This is also referred to as "sandboxing". You make a formation with gear, attack the present truck, look at the Damage done and DMG taken and rearrange your formation configuration to try to improve this.

A great show of this is by the amazing Warzone Wrecking Crew: https://youtu.be/O_cjl6QGctQ?si=-NrjpRLqQHLyt8a9

Arena

This one is simple - just change up your formations and hope you hit the squad you're looking at on the opponent.
