A system for testing a blood glucose measurement engine includes a host device emulator having a measurement engine port communicatively coupled to a communications port and electrically coupled to a power supply. A diagnostic computer may be communicatively coupled to the communications port of the host device emulator. The diagnostic computer may include a processor and a memory having computer readable and executable instructions. When the blood glucose measurement engine is communicatively coupled to the measurement engine port, the host device emulator simulates connection to a host device by facilitating the communication of signals between the diagnostic computer and the blood glucose measurement engine. The processor executes the computer readable and executable instructions to: transmit control signals and diagnostic signals to the measurement engine, receive and analyze data signals transmitted from the measurement engine, and monitor a glucose measurement process performed by the measurement engine.
