Claim 0:
1. A test environment determination device, comprising:
an element selection unit that selects 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 (ECU), 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 acquisition unit that acquires operation information on the test environments;
a usage cost calculation unit that sets hardware-in-the-loop environment cost values and software-in-the-loop environment cost values; and
an environment selection unit that selects 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 one or more test environments comprise a hardware-in-the-loop environment and a software-in-the-loop environment.
