RE: Unit tesing with Unity and CMake in nrf connect SDK on windows

Hello,

Apologies for the delayed response. I was away attending workshops. As far as I know, the VS Code extension doesn't integrate with Twister for unit testing, and we currently have no plans to support Twister.

Kind Regards,

Hi Abhijith,

Thanks for the reply..

I have tried to run the twister with WSL Still it skips the tests. Just like in windows

is the unity test examples from nordic(/ncs/nrf/tests/unity/example_test/) tested with Twister on nordic side ?

Or are you guys using west to run the tests :)

Regarding

Hello,

[quote user=""]from my understanding its not possible to run the twister/build for native_posix in windows. Is it correct ?[/quote]

Yes, you're right. The native_posix board in Zephyr is meant to run on POSIX-compliant systems like Linux or macOS. On Windows, you can use the Windows Subsystem for Linux (WSL), but it won't run directly on Windows.

[quote user=""]After running the Twister (in my case "python C:\ncs\v2.7.0\zephyr\scripts\twister -T . -p qemu_cortex_m3"),seems like twister skips the test cases. Please see the attached screenshot.[/quote]

From the screenshot, it seems that Twister is skipping the test cases instead of running them. I'm not entirely sure why this is happening maybe it's due to the test case configuration. I suggest double-checking the testcase.yaml file to see if there are any constraints causing the skips..

[quote user=""]We also have second source project with another chip manufacturer.There also we use Zephyr. Is it possible to use the same framework(Unit testing with Unity and CMake in nrf connect SDK) for other zephyr projects ?From my understanding the CONFIG_UNITY in prj.conf is only available in the nrf connect sdk environment,not in Zephyr[/quote]

It's true that the CONFIG_UNITY and the Unity-based unit testing framework in the nRF Connect SDK is designed specifically for the nRF ecosystem and isn't available directly in upstream Zephyr. However, I think you can still use the same general framework (Unity, CMock, CMake) for unit testing in other Zephyr-based projects, though you might need to set it up manually.

If you'd rather use a native Zephyr solution, consider switching to ZTest, which is built into Zephyr and designed for testing on different platforms. You can check out this page from Zephyr for more details.

Kind Regards,
