A testing apparatus (100) for testing visual systems is specified. The testing apparatus comprises a moveable holding device (110) for holding a viewing unit (200) of the visual system, a position detection unit (120A, 120B) for detecting the position and alignment of the viewing unit (200), and a test-conducting unit (140). The holding device (110) is designed to perform a movement of the viewing unit (200) with a rotational degree of freedom. The position detection unit (120A, 120B) is designed to detect the position and the alignment of the viewing unit (200). The test-conducting unit (140) is coupled to the position detection unit (120A, 120B) in such a manner that a detected position and alignment of the viewing unit can be transmitted to the test-conducting unit (140), wherein the test-conducting unit (140) is also designed to determine a field of view as a function of the detected position and alignment of the viewing unit (200). The test-conducting unit (140) is furthermore designed to read in a field of view actually displayed by the viewing unit and to compare the determined field of view with the read-in field of view. The testing apparatus thus enables an accurate and reproducible testing of visual systems, in particular of augmented visual systems.
