Including Preprocessor Directives in Unity/CMock

[aivilo]

We have unit testing working with the Zephyr Unity/CMock setup, however the test runner (test_runner_generate) ignores preprocessor directives (#ifdef) and removes them when creating the runner_x.c file. This leads to the runner_x.c file including both the #ifdef and #else lines. 

We tried to modify the unity_cfg.yaml file with the line below as specified in the Ceedling documentation (https://github.com/ThrowTheSwitch/Ceedling/blob/master/docs/CeedlingPacket.md) but it had no effect.

:project:

  :use_test_preprocessor: TRUE

Is there another setting that can be configured, and are the Ceedling settings even available for the Unity/CMock framework available?

NCS Version: 2.4.2

Hi, 

Thank you for your suggestion. I tried adding the defines to the yaml file, however the issue still persists.

I have been editing the file \nrf\tests\unity\unity_cfg.yaml and it has a direct impact on build\mocks\unity_cfg.yaml. Should I add the changes in another file? Or add a project.yml file as the stack overflow post suggests?

Thank you!

Hi,

 

Did you try adding this to your project yml file?

 

Kind regards,

Håkon

Hi,

Yes, I have tried that. However, the build does not see those changes. Where should the project.yaml file be and is that the correct name for the compiler to include it? Currently I have it in my project folder.

Hi,

 

Do you specify a folder that holds project.yml in the root-folder of your test?

I would recommend that you check the output to see if it has parsed the file or not.

 

Kind regards,
