A device includes a holder, a cover, a socket, a number of first pins, and a number of second pins. The holder defines a holding groove in its upper surface for holding a voice coil motor. The holder also defines a pin groove in its right sidewall communicating with the holding groove. The voice coil motor has electrodes facing the pin groove. The cover covers the upper surface to fix the voice coil motor in the holder. The socket is attached to the right sidewall. The first pins are fixed in the socket to connect with the electrodes. The second pins are connected with the first pins. The second pins connect with a number of third pins of a testing fixture for testing the voice coil motor when the device is assembled into the testing fixture.
