Remote terminal test method, system and proxy server

The invention discloses a remote terminal test method. The method comprises the following steps: a remote terminal test system provides a user with an analog terminal operation interface, as well as various selective analog terminals; when the phenomenon that the user selects at least one analog terminal on the analog terminal operation interface is detected, the remote terminal test system establishes communication connection with a practical terminal corresponding to the selected analog terminal through a proxy server; when the user operates the selected analog terminal, the remote terminal test system acquires the present screen content of the practical terminal in real time through the proxy server according to the operation of the user; and the remote terminal test system displays the acquired present screen content on the analog terminal operation interface in real time, so as to respond to the operation of the user. The invention also discloses a remote terminal test system and a proxy server. By adopt
