An apparatus and a method for testing spoke sensor are disclosed. A drive unit is started to rotate a test disc to a predetermined rotation speed. A module test unit is electrically connected to a spoke sensor under test of a spindle motor module. The module test unit is started to drive the spoke sensor to detect the spoke signals of the test disc and record the number of detected spoke signals. Within a test time, a comparison unit is used for comparing the number of spoke signals with a threshold, and only when the detected number is larger than a threshold will the spoke sensor be assembled to the product. Thus, the product quality is assured.
