fff VS benchmark

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

I'm aware of one by Google that I used a couple times, but IMO it's better to capture real runtime data from a fully-operational process than to carve out the benchmarkable bits and test them in isolation, so I track information during program testing and print it all to a log instead of using things like that.

If you just want to do some quick benchmarks, you can just use std::chrono::high_resolution_clock::now(). Call it before the code that you are benchmarking and then immediately after. Take them away and you have your duration. If you want to use a proper benchmarking tool then I can totally recommend Google Benchmark. Fantastic benchmarking tool. Honourable mention would be Quick Bench which is an online tool that uses Google Benchmark.

I tried to install google benchmark(https://github.com/google/benchmark) in my ubuntu machine by :

We don't know if it's a lie until we verify it and that's not difficult, you have a quicksort implementation in a couple of languages, you'll need to pass the necessary parameters to show the time needed by a function call to execute to the compiler or interpreter or you may use use a library(like benchmark for C++) and you're good to go.

If you are uncertain about the performance characteristics of a function you should ALWAYS benchmark it. Googles Benchmark library is wonderful for quick micro benchmarks. For more complex things, perhaps look into profiling and then look at invocation counts of copy constructors.

Your compiler may be optimising away your loop, there. I typically use a micro-benchmarking tool for these types of tests. You could try Google Benchmark. It’s available in most OS’ package managers, but pretty easy to build from source if not

C++: C++ has quite a number of benchmarking libraries some of the recent ones involving C++ 20's flexibility. The most notable being Google Bench and UT. C does not have many specific benchmarking libraries, but you can easily integrate C code with C++ benchmarking libraries in order to test the performance of your C code.
