No more than a visual examination of the component!
Build a compatible circuit that utilizes the features of the component in question.
Observe the results.:confused:

You need at least a multimeter...

I've tested batteries with a small motor and a soda bottle cap glued on the end of the shaft. Stick a small piece of plastic against the ribbing of the cap and then run the motor with the battery. The stronger the battery the higher the pitch produced by the plastic strip and the ribbing of the cap.

Now I wouldn't call a motor a test "instrument", but I would agree it's being used as one.

In my youth I tested using a coil of magnet wire and a magnetised sewing needle.
I would still have to call that an instrument.
