A test board includes a socket, a mounting test circuit, and a relay. An analog core embedded application processor is installed into the socket. The mounting test circuit has a same configuration as an environment where the analog core embedded application processor is actually used. The relay disconnects the mounting test circuit from the socket in response to a first control signal when a vector test is performed on the analog core embedded application processor, and that connects the mounting test circuit to the socket in response to a second control signal when a mounting set test is performed on the analog core embedded application processor.
