1. A multichannel test clip for testing of a neurostimulation lead, the test clip comprising: a pair of opposing members pivotally coupled together, each member having a jaw along a distal portion thereof and a handle along a proximal portion thereof, the pair of members being movable by manual articulation of the handles between an open position in which opposing jaws are spaced apart to receive a proximal portion of the neurostimulation lead and a closed position in which opposing jaws are adjacent one another, wherein the pair of opposing members are biased by an urging member towards the closed position so as to secure the proximal end of the lead between opposing jaws when in the closed position; a lead connector disposed along an inside of opposing jaws of the pair of opposing members and defining a channel or receptacle having a plurality of electrical contacts arranged therein so as to electrically couple with a plurality of electrical contacts on the proximal end of the lead when secured between the opposing jaws in the closed position within the channel or receptacle, wherein the plurality of electrical contacts of the proximal end of the lead correspond to a plurality of neurostimulation electrodes on a distal portion of the lead such that each electrical contact of the plurality of electrical contacts in the channel or receptacle correspond with a neurostimulation electrode of the plurality of neurostimulation electrodes of the lead; a proximal cable connector having a plurality of connector contacts that correspond to the plurality of electrical contacts of the lead connector, the proximal cable connector being configured for electrically coupling with a corresponding connector of a programming device; and a stimulation cable having a plurality of conductors extending therethrough and electrically coupling corresponding electrical contacts of the lead connector and the proximal connector so as to provide a separate channel between a respective neurostimulation electrode of the lead and the programming device to allow testing of each of the plurality of neurostimulation electrodes with the programming device, wherein the clip is configured such that each channel allows stimulating and measuring with the programming device concurrently.
