The utility model provides a warping testing device, and relates to the technical field of cover plate glass production. The warpage test device comprises a test platform, which is provided with a first plane used for supporting glass to be tested; the lifting driving mechanism is mounted at the side part of the testing platform and is provided with a lifting part capable of reciprocating along a first direction perpendicular to the first plane; the test plate is mounted on the lifting part so as to be driven by the lifting part to reciprocate in the first direction, and the surface, facing the test platform, of the test plate is a second plane parallel to the first plane; the plurality of sensor units are sequentially installed on the second plane and form a sensing area, and the sensing end of each sensor unit faces the first plane; wherein the position of the to-be-tested glass corresponds to the position of the sensing area in the first direction, and the sensing area is not smaller than the area occupied
