It's called a DMM or digital multimeter. It's a testing tool that will allow you to test for DC voltage, ohms, short circuits, and polarity. It has many other functions, but those will be the ones you use the most frequently in this hobby. Mine is a little pricey, but they come in all price ranges (starting at about $10).
If you're a newb, you'll just have to trust that this toll will save you mountains of time and possible equipment failures.
