Mocking peripherals for unit testing

[gmb]

I have been experimenting with using unity as a unit-testing tool, together with ceedling and cmock, against code developed with SDK2.1. I have only succeeded in getting trivial tests working before running into issues involving drivers. It seems as if cmock fails on static inline functions.

Has anyone managed to properly harness a project built on SDK2.1 or SDK2.2? I am not specifically tied to unity/ceedling/cmock. I would be happy with any tool that manages to penetrate the layers of register definitions and operations.

Hi Greg,

I'm trying to do the same thing as you, use ceedling to write some tests for drivers/applications/... that use the KSDK.

Unfortunatelly, I also have issues with 'static inline' functions.

I don't know how you did it, but I just did a workaround by declaring my own mock-headers of the KSDK.

The API of the SDK won't change that quick/much so I guess it's safe to copy the original KSDK header and replace the 'static inline' functions with 'normal' function declarations (without static inline).

That way, CMock recognizes them as a regular function and makes mocks out of it.

And if the API of the SDK changes, I would have to change my code anyway, so I guess this is a 'safe' workaround.

If you found another tool that can better handle this, let me know.

Thanks,

Hope this helps,

KR,
