Testing with Unity against native_posix with enabled Oberon

[strmer]

I'm trying to add the unity test integration to our project, but failing to build, since the project has a dependency on nrf_oberon

For the sake of completeness, the project is based on latest nRF_Connect_SDK and build with VS code on macOS Big Sur, which should not be relevant for this issue.

Running a test build native_posix as recommended here failed!

$ west build -b native_posix -t run --pristine

Hi,

 

Which example are you trying to run?

oberon library is a static library for arm, specifically these cortex m targets:

Kind regards,

Håkon

I'm not trying any example directly, just setting up the unity tests into an existing project.

But I think it might be reproducable when adding `CONFIG_NRF_OBERON=y` to the unity example inside the nrf sdk

But since all oberon artifacts are build for arm only, is there any chance to get the unity and cmock running here?

Not all unit tests can be run on the posix target, especially when you have a dep on a hardware peripheral. If you use qemu_cortex_m3, you can get some of the peripherals running with unity, but its not guaranteed to work with all combinations.

Here's an older thread on the matter: https://devzone.nordicsemi.com/f/nordic-q-a/70127/unit-test-unity-cmock---cmock_handle-native_posix-still-returns-errors

 

Kind regards,
