nRF Connect with Zephyr Testing Framework: Mocking central role connection to test BLE peripheral UART

[rgangwan]

Hello!

I am trying to develop tests with Zephyr Ztest framework to determine proper code coverage. Part of my functions invoke BLE NUS send and receive. For this to work properly and verify BLE portion is correct, I'm trying to find ways to mock the central connection that the device would connect to.

Are there any example codes or methods that I could mock the central connection that the testing code would connect to? This is so that the mocked central role can do things like enable TX notifications so the nus_send would go through.

Thanks!

Abhijith,

Thanks! I will check them out.

I am curious how peripheral_uart was tested (if it was tested through some automated testing tool). I found babblesim and assumed that would work, but if there's some other tool that can help with this problem I would love to try that as well!

Regards,

Rahul

Hello,

I recommend you to use the Zephyr forum as they have official samples and support for this. Since we don't support this, I guess it's not been tested or verified here.

Kind Regards,
