    when i have a system of only dependant sources and i want to find its norton /thevenin
    representation i need to add a testing source on the ports from whome we want to see the reaction

    It is irrelevant. If you put a voltage source, you must evaluate how much current it supplies to the circuit in order to calculate its equivalent impedance. If you use a current source, you must evaluate the voltage across its terminals do do the same calculation.
