The present invention relates to the field of laser testing technology, and discloses a laser testing device and a testing method. The device comprises: a test table, on which a universal clamp assembly for clamping a laser is fixedly installed, the universal clamp assembly is provided with a laser rangefinder, and a movable seat is slidably installed on the test table. The present invention can form an inscribed circle inscribed in the four reflective plates through the rotation of four reflective plates, and the diameter of the inscribed circle is equal to the maximum spot diameter of a laser beam of a qualified laser projected onto a horizontal plane where the reflective plates are located. When the laser beam passes through the inscribed circle and does not irradiate the reflective plates, it means that the laser is qualified and the position is not offset. If it irradiates the reflective plates, correction is required. If there is still a laser beam irradiation point on the reflective plates after correction, it means that the laser is unqualified, thereby ensuring that the qualified laser can project the laser beam onto a spot analyzer for spot analysis without position offset.
