The invention provides a method for testing the jitter and slippage of a belt of an engine gear train and a swinging angle of a tension roller. The belt jitter quantity D of belt gears can be obtained by adopting a laser displacement sensor to acquire the belt jitter displacement of a belt middle position between the belt gears; a laser rotation speed sensor is utilized to test the rotation speed VDriver of a driving gear and the rotation speed VDriven of a driven gear, and the belt sliding rate S of the driven gear is calculated through the formula as shown in the specification, wherein VDriver is the rotation speed of the driving gear of the gear train, VDriven is the rotation speed of the driven gear of the gear train, and I is the transmission ratio of the driving gear and the driven gear; subsequently a laser acceleration sensor is utilized to acquire an acceleration time domain signal in the swinging direction of the tension roller, the acceleration time domain signal is obtained through fast Fourier transform, the peak value, namely, the amplitude value A, and the frequency f at the peak value are found out; and the maximum swinging angle theta of the automatic tension roller is calculated according to a formula as shown in the specification.
