A testing apparatus for testing electrical components and/or conductor track structures. The testing apparatus includes: a multiplicity of testing locations, each receiving an electrical component and/or a conductor track structure; a selection device for selecting one of the testing locations; electrical lines disposed in rows and electrical lines disposed in columns for the supply of an alternating voltage to the component or structure, situated at the selected testing location; Z diodes for the electrical connection of the respective component and/or structure at the respective testing location via one of the Z diodes to one of the rows of electrical lines; a signal generator developed to generate a test signal that has a voltage signal as the sum of a square wave signal and a wave-shaped signal; and an electromigration device for applying a direct voltage signal to the components and/or structures to bring about electromigration in the components and/or structures.
