   Very useful C testing library that our embedded developers use along with the principles and methods described in the book 'Test-Driven Development for Embedded C':

   Hmm, sounds like you might be automating tests on the target, scripted from the PC. There's a place for this, but I'd call that automated integration/system testing, not unit testing.

   Unit testing was traditionally considered impractical for embedded systems, because the code is so closely tied to the hardware. However, with proper architecture and unit test frameworks that simplify your life, it's quite feasible, and indeed enjoyable.

   You write unit tests that exercise your embedded code, compiled for the PC, not the target. This ensures your code is portable.

   I use the Unity/CMock/Ceedling framework when I'm writing in C, and CppUTest when I'm writing in C++.

   I HIGHLY recommend the video courses taught by the guys at ThrowTheSwitch.org (the authors of Unity/CMock/Ceedling). See https://www.throwtheswitch.org/dr-surlys-school

   I read and enjoyed James Grenning's book, Test Driven Development for Embedded C, but it didn't really click for me until I took the video courses mentioned above. In the second course, you code an entire simple but realistic embedded project in TDD fashion.

   "Test-Driven Development for Embedded C" by James W. Grenning.

   https://pragprog.com/book/jgade/test-driven-development-for-...

   It's very well written and I've used the unit testing approaches described there in several projects.

   I really enjoy CppUTest. It was written by James Grenning who is one brilliant engineer if you ask me. He also wrote the fantastic book "Test Driven Development for Embedded C" which I would highly recommend to anyone, even non-embedded developers.

   I used CppUTest on a c++ project to test algorithms for image and video manipulation. It worked fantastically, very easy to learn, and it helped test drive and optimize the algorithms. Highly recommended.

   Edit: fixed typos, typing on phones is hard.

   Have a look at test driven development for embedded C by James Grenning for a viewpoint of how TDD might work in the embedded world. I found it to be a great resource.

   I respectfully beg to differ with your first statement. I TDD in embedded and low level code, well, always. There is a great work on this by Grenning, worth reading by anyone who wants to understand TDD better, whether it is for embedded C or any other type of application.
