Abstract: To provide a mobile terminal testing apparatus capable of facilitating a change or rearrangement of a pseudo base station performing carrier aggregation and efficiently performing a test of the carrier aggregation. The mobile terminal testing apparatus includes an operation unit 11 that receives an operation input from a user, a display unit 12 that displays an image, and a control unit 14 that causes the display unit 12 to display an identification name of a pseudo base station of carrier aggregation of a scenario that has already been created, causes the identification name of the pseudo base station to be changed by an operation of the operation unit 11, and causes a scenario to be created on the basis of a configuration of the changed pseudo base station.
