what kind of test you are looking for?

cheap tester circuits incl. most multimeters only check for change in current.
this is why they are unreliable and can be fooled easily - for example just insert
resistor into C and E terminals instead of a transistor and you will see "gain".
imho, this is useless, it is better to build a circuit that does something specific
such as an oscillator for example. for this to work component must have gain.
here is an example of such tester:
