Disclosed are a system for testing a wireless terminal and a method for controlling the same. The system includes: a device under test being a wireless terminal; a reflecting surface, configured to totally reflect one or more wireless signals emitted by the wireless terminal; a rotation mechanism, configured to drive the device under test to rotate; a test antenna, configured to receive one or more wireless signals reflected; and an absorbing screen. The device under test, the test antenna and the reflecting surface correspond to a same ellipsoidal surface, the device under test and the test antenna are arranged at two foci of the ellipsoidal surface respectively, and the reflecting surface is arranged on the ellipsoidal surface. The system has advantages of small repetition error of test results, stable test results, high testing efficiency, and low cost.
