PURPOSE: A method for testing units for a vehicle is provided to perform valuation of durability and life of the units of the vehicle in the same load condition as a real vehicle by making excitation signal having the same fatigue damage as a real vehicle condition. CONSTITUTION: A method for testing the units for the vehicle includes the steps of making unit testing data according to roads on which a real vehicle travels, processing the real vehicle unit testing data, operating fatigue damage of the processed real vehicle unit testing data through a prescribed operating method and calculating the fatigue damage after deleting non-damage data, generating and outputting excitation signal required for the unit test from the calculated fatigue damage, valuating durability and life of the unit through excitation signal output from the above step.
