Unity Test API VS minUnit

There are plenty of good IDE in 2024 for any languages; C included.

For the IDE itself, the big choices are between Jetbrains CLion and VSCode. If you are familiar with Jetbrains product for another language, stick to it. Same for VSCode, if you’re use to it, just install the right plugins.

I personally prefer Jetbrains product because it is working without selecting/installing all the plugins. Some people likes to tweak their environment. So, I don’t use a lot of plugins on the IDE.

I use VSCode only when I have multiple stack in the same project (typically Flutter project which include the Dart part and the native part). In that case, VSCode is more practical.

In the embedded world, there is also Kiel for ARM embedded development. (https://www.keil.com/). I was never be able to use it. It is really unnatural to me but a lot of embedded C developers love it.

Regarding the dev tools, I prefer to use tools that are multi platform and widely used. So, the dev tools include CMake, make and GNU C compiler. It is a pretty common toolkit that covered my needs so far.

Unit tests are written with Unity Test Framework (https://github.com/ThrowTheSwitch/Unity). It is simple and allow to be executed on the target if required; which is practical for embedded development.

You shouldn't need a configuration file to write tests with Unity. You are using Unity from Unity on Github right? You can use YAML files to along with some helper scripts Unity and related tools provide, but it doesn't sound like you are there yet.

First, for context, as part of my internship, I'm writing unit tests for functions from a hardware manufacturer provided C++ library. This particular code is testing if the relevant function returns a unique location ID for each hardware device. The test assert macro I'm using is from the Unity test framework C library.

I use Unity Fixtues + FFF + CException framework.

Edit: I also tried Googling "list of Unity test framework macros" and found this, which is kind of helpful, but still doesn't actually explain how the correct syntax for specific macros or precisely what they do. I guess basically, I'm looking for something similar to the entries on cppreference.com, but for the Unity macros instead of the standard library functions for C++.

I know Unity is used in the embedded industry, I also use it for my own personal projects. It’s great and does everything I need.

If you're using the ESP-IDF framework, it already comes with Unity. It's easy to use, and you have the Test Driven Development for Embedded C book as reference.

As far as testing, debugging, and makefiles. I sort of just learned those things on my own as I needed them mostly. I've been using minunit for testing. Super simple. But Jacob Sorber on YouTube has a ton of videos going into those topics which are good enough to get you started on them.
