fff VS utest.h

Only cool framework in my opinion. I wish I had the guts to delve so deeply into Variadic Macros.

You can use GoogleTests. Also, if you have C functions which need to be mocked, you can try using the FFF framework along with with gtest.

I use Unity Fixtues + FFF + CException framework.

For news reading, surely, I'd go with newsboat, perfect for this. Newsboat also fetches Odysee and Youtube channels, and you can integrate mpv to it to watch the videos. No ads, nothing. For file manager, I'm using fff, very minimal and relatively easy to configure.

Also recommend checking out fff.

Everything else was covered: Ceedling+Unity+CMock for Unit Testing in C, CppuTest or GoogleTest or other options for C/C++. FFF is also useful when mocking. If you test and develop your modules correctly, they should when they are in your application. If you are developing using an Event-Driven Framework like QP or QML, then I would not test anything to do with the framework, but the functions that are called in each event. Same thing if you are using an RTOS, test what's inside your threads/tasks.

Interesting! Always nice to see more of these kind of test tools for C. I'm currently using fff and Unity

Doesn't really have CMake integration, which is a big downer. You could try utest.h, which is a pretty minimal (as the name suggests), but featureful testing library. It still needs you to declare the main, but is that really such a problem?

the header-only https://github.com/sheredom/utest.h might be worth a shot if you trying to keep things compact.

Sprinkle your console apps with UTEST test's.
