Is there a way to test individual cree LED prior to installing them?

So I just ordered my kit, but I started thinking what if a LED isn't working. Is there a way to test it?

I don't want to install it, solder everything together, and then nothing works...

If they are 3v leds you should be able to hook them up to a 3v coin cell battery to test them, or more common aa's or aaa's.

do I just use some 20/22g wire + to + - to - ?
