1. An operation test method of a plurality of base stations to which a terminal station is connectable, the method comprising:
collecting, as environment information, a radio environment represented by a signal received at a plurality of radio communication units from another base station of the plurality of base stations, each of the plurality of radio communication units being switchable between a normal mode in which the radio communication unit performs radio communication as a base station and a subordinate mode in which the radio communication unit performs radio communication as a virtual terminal station;
calculating test conduct information for each of the plurality of base stations based on base station performance information representing a performance of each of the plurality of base stations and the environment information; and
conducting an operation test of each of the plurality of base stations by, based on the test conduct information, by setting any of the plurality of radio communication units to the normal mode, switching the plurality of radio communication units of the other base station to the subordinate mode, and performing radio communication with each other.
