A test apparatus for testing quality of serial interface communication between two CPUs of a dual-mode handset includes a processor module and a switch module. The processor module includes two serial ports, each serial port includes an output connector and an input connector, and the two input connectors respectively connected to the two CPUs. The output connector of either serial port connected to either CPU via the switch module. The processor module controls the CPU connected to the output connector to work when the switch module is switched on, and checks data transmission between the two CPUs via the two input connectors when the switch module is switched off.
