The invention relates to a method for testing the correct operation of electrodes in electrostimulation garments and to a device for carrying out said method. The method comprises the operations of: optionally placing the garment on a test support； connecting an electrical source or electrical generator to connectors of the garment； generating an electrical pulse that transmits electricity to the connected electrodes, with a voltage, normally, of up to 9 V, and with a pulse frequency, normally, of up to 500 KHz； applying to the external surface of the electrodes a radio frequency sensor or antenna that reads the signal from the electrical field generated by the electrical source； and comparing the values from the measurement with reference values to determine if the garment is in a correct state or if same is in an incorrect state and needs to be repaired or discarded. The device comprises a generator (21) for generating a pulsing electrical signal, a connector (30) for connecting said generator (21) to the garment (1), a receiver device (22) and a circuit (32) for measuring the captured signal.
