To ensure the accuracy of C API, all interfaces need to implement function level unit test at least. According to the object define, all implemented unit test cases are located in this folder.
The generated binary ov_capi_test included the unit cases about all implemented C API interfaces.
If developer wrap new interfaces from OpenVINO C++, you also need to add the unit test case in the correct location. Here is an example wrap C++ interface to C wrap core.
Create unit test case for this interface. At first, this interface is for core operation so the location should at ov_core_test.cpp. Also, the interface has default parameter so need to make unit test case for parameter missing. The final based function level test like:
