Classification: CPC G | IPC G

Claim 7:
8. A test environment determination method for a computer to select a combination of a test target and a test environment suitable for executing a test case, the computer including an arithmetic device that executes a program and a storage device that can accept access from the arithmetic device, the test environment determination method comprising:
an element selecting step of selecting, by the arithmetic device, one or more test targets and one or more test environments for executing a test case based on target requirements described for specifications of an electronic control unit, which is a test target, and environment requirements described for specifications of a test environment for simulating an external environment of the test target;
an environment operation information acquiring step of acquiring, by the arithmetic device, operation information on the test environments;
a usage cost calculation step of setting hardware-in-the-loop environment cost values and software-in-the-loop environment cost values; and
an environment selecting step of selecting, by the arithmetic device, a combination of the selected test target and the selected test environment based on the acquired operation information, the hardware-in-the-loop environment cost values and the software-in-the-loop environment cost values, wherein the test environment comprises a hardware-in-the-loop environment and a software-in-the-loop environment.
