Pool/spa combo

[dumbcluck]

This may be a stupid question, but after all I am a dumbcluck.
Since I have a spa that overflows into the pool and shares equipment, is it normal to just test my water in the pool since they share water or should I be testing both bodies of water separately?

The water should be effectively the same if you are constantly adding water to the spa and spilling into the pool.

That's what I figured. Just wanted to see if it was considered normal.
Thanks
