You can easily check Dir pins with a voltmeter, just jog one way and then the other and the Dir pin should change between 0v and 5v or vice versa.
The Step pins can also be looked at whilst jogging but you will only see a small change in voltage, if set active High you will see the volts go from zero to possibly a few hundred mV, if set active Low you may see the 5v drop a bit when jogging but really a scope is needed to see exactly whats happening on the step pins..
