s2: the control unit (2) continuously sends a second-stage gear shifting instruction to the second air flow control unit (122), and ventilates the second air flow control unit (122) to provide a second resistance for engaging a second-stage gear in advance; the control unit (2) sends a second-stage gear shifting instruction to the gear shifting executing mechanism (4) to be tested, meanwhile, the second air pressure sensing unit (132) monitors the air pressure value in the air path in real time to obtain second-stage air pressure data, the second-stage air pressure data is fed back to the control unit (2), the second-stage displacement sensing unit (112) monitors whether the gear shifting executing mechanism (4) to be tested is in place or not in real time to obtain second-stage stroke data, the second-stage stroke data is fed back to the control unit (2), and the control unit (2) obtains the second-stage air pressure data and the second-stage stroke data; and (5) completing the testing process of the gear shifting executing mechanism to be tested.
10. The method of testing according to claim 9, further comprising the steps of:
s31: the control unit (2) continues to sequentially send gear shifting instructions to the second group of test units and the third test unit to obtain a plurality of groups of air pressure data and travel data;
s32: and repeating S1-S31 until the test frequency requirement of the gear shifting executing mechanism to be tested is met.
