Does Esr capacitor tester, test all different types of capacitor or just electrolytic capacitor?

I am going to say all.

The one I use does not require a polarized capacitor. However most non-electrolytic caps will be low capacitance and I'm not sure how sensitive the meter is when testing such a low capacitance. It might require a special design and build to accomplish this.
