How often to do tests?

[poolnoobgrandma]

So, pool today is sparkling clear blue. FC is 8.5, Ph is 7.6.
I forgot and dumped the water before testing for CC (I keep doing that.. then have to redo the whole thing...). I can go back and do the CC and all the other tests, (did the whole suite yesterday) but do I really need to?
If everything looks and smells good, how often do I need to do all the tests?

Results from yesterday
FC 6
CC .2
PH 7.2
TA 40
CH 290
CYA 30-40 (result from 7/4) -- how often do I need to test this if I don't add any?

Thanks!

I test PH, CC, and FC every 3 days or so. I run a full set of tests monthly.

Testing won't be such a chore if you use only 10 ml water and one scoop of powder so each drop counts as .5
Likewise for the CH. 10 ml water, 10 drops, 3 drops, and then each drop of 12 counts as 25.
