Unit testing using twister with Unity and CMock always passthrough mocked functions

[svo]

I have a project for the NRF5340 with SDK 2.6.1. I test the code with twister using Unity and CMock. That works great. But now I have to adapt the unity_cfg.yaml (which is generated via the ruby ​​scripts) for certain tests, for example to deactivate passthrough.

I have found the following possible solutions:

1. Via CMakeLists.txt: Generate mocks using

   CMock_Handle(...NO_PASSTHROUGH TRUE)

   . According to the official documentation (Testing with Unity and CMock), there is only
   

   cmock_handle()

   , which only allows the include file and an optional out path.
2. cmock.yml in the test directory where the CMakeLists.txt is located:

   :cmock: 
       :passthrough: false

   . This option is not available in the cmock_config.rb. In addition, the contents of my cmock.yml is not merged, my file is simply ignored. It's still good for me to know how I can set other options (e.g. :treat_inlines: :include) via this.
3. Specify my cmock.yml via environment: via shell environment or "twister ...... -x CMOCK_CONFIG=<path>" or "twister ...... -x UNITY_CONFIG=<path>". Doesn't work.
4. Environment variable CMOCK_PASSTHROUGH=false. Doesn't work.

I checked it by choosing a function with asserts and making sure that I get stuck there (CONFIG_ASSERT=y).

I hope someone can help me.

Thanx in advance,

svo

Hi!

This is not something we are familiar with.

Maybe someone in the Zephyr community discord knows about this.
