The invention relates to a method and system for testing the rotating speed of an electronic water pump. The electronic water pump rotating speed testing method comprises the steps that the feedback rotating speed and the actual rotating speed of the electronic water pump during stable operation at the requested rotating speed are obtained; acquiring a request rotating speed, a feedback rotating speed and an actual rotating speed of the electronic water pump at the same moment in the variable-speed operation process; the accuracy of the feedback rotating speed of the electronic water pump is comprehensively judged according to the difference value between the feedback rotating speed and the actual rotating speed of stable and variable-speed operation. The invention further provides a system for testing the rotating speed of the electronic water pump, the system comprises the ECU used for being connected with the electronic water pump to be tested, the rotating speed sensor, the data acquisition module, the ET
