Need help with MLCC capacitors : r/AskElectronics
Yes, you can test them with a multimeter (if your multimeter is able to measure capacitance). The continuity test can be dione with the component still soldered on teh board, the capacitance measurment MUST be done with the component desolderd (or at least one of the pad desoldered, but with SMDs it is easier to desolder the whole SMD).

$begingroup$ You have to consider how much current your power supply can handle, and certainly the ripple current and voltage rating of the capacitor. If your supply along with it''s output impedance, layout impedance and the ESR of the capacitor gives you a charging current that''s acceptable then you don''t need a resistor in series.

Do electrolytic capacitors have a limited shelf life?
Having said that, there is some behavior with electrolytics where the plates are "formed" when power is first applied and after sitting idle for years may need to be re-formed again. This really hasn''t been an issue with capacitors for decades, so unless you''re trying to use a bunch of caps that have been sitting on a shelf since 1945, I wouldn''t worry about it.
