1. A test board comprising: a socket into which an analog core embedded application processor is installed; a mounting test circuit that has a same configuration as an environment where the analog core embedded application processor is actually used; and a relay that 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, wherein the vector test is performed on the analog core embedded application processor when the first signal is enabled, and a first test result is provided to an automatic test equipment (ATE), the first test result indicating a result of the vector test, and wherein the mounting test circuit comprises: a first memory that stores a booting program for booting the analog core embedded application processor and a test program for the mounting set test on the analog core embedded application processor; a second memory into which the booting program and the test program are loaded; and a buffer coupled to the first memory, the second memory and the relay.
