The invention discloses a testing assembly for electrostatic discharging testing. The testing assembly is connected with a metal probe for performing electrostatic discharging voltage testing on a to-be-tested object. Furthermore the testing assembly comprises a probe connecting element and an assembly body. The probe connecting element comprises a guiding segment and an insulating segment. The guiding segment is used for receiving electrostatic discharging voltage and is connected with the metal probe. The insulating segment is connected with the guiding segment and is composed of at least one insulating material, wherein the product between length of the insulating segment and dielectric strength of the insulating material is larger than the electrostatic discharging voltage. The assembly body is connected with the probe connecting element.
