description Provided is a testing apparatus including: a light emission control unit which causes a plurality of light emitting elements to be tested to emit light; a light measurement unit which receives the light emitted from the plurality of light emitting elements and measures wavelengths of the received light; and a determination unit which determines whether there is an abnormality in at least one light emitting element on the basis of intensity distributions of the wavelengths of the light, which is emitted from the plurality of light emitting elements, measured by the light measurement unit. The testing apparatus may further include: a light source; an optical system which irradiates the plurality of light emitting elements with light emitted from the light source; and an electrical measurement unit which measures a photoelectric signal obtained by each of the plurality of light emitting elements photoelectrically converting the light radiated by the optical system.
