Top 10 C unit-testing Projects

  • Criterion

    A cross-platform C and C++ unit testing framework for the 21st century

    • Project mention: Show HN: RK Test, a Google Test style library written in C99 | news.ycombinator.com | 2023-12-11

    I really like Google Test, but am planning on doing some embedded development in C, where I sometimes find it awkward to test C code using a C++ library.

    Therefore, I wrote a small unit test library closely mimicking Google Test. It consists of two source files, "rktest.c" and "rktest.h", and is about 1k lines of code and written in C99.

    It uses a trick for self registering tests by placing pointers to the unit test functions into a known place in program memory, that I first learned about from https://github.com/christophercrouzet/rexo/ and https://github.com/Snaipe/Criterion/.

  • Muon

    A Micro (1k lines of code) Unit Test Framework for C/C++ (by jasmcaus)

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • cauldron

    A collection of single-file C libraries. (generic containers, random number generation, argument parsing and other functionalities) (by camel-cdr)

  • c_koans

    C Koans

  • libGimbal

    C17-based extended standard library, cross-language type system, and unit testing framework targeting Sega Dreamcast, Sony PSP and PSVita, Windows, Mac, Linux, Android, iOS, and WebAssembly.

    • Project mention: Object-oriented Programming with ANSI-C [pdf] | news.ycombinator.com | 2023-06-21

    I'm a huge academic fan of what GTk has accomplished (thanks to their GObject type system), and as much as I know the C89 crowd who thinks macros are all evil probably abhor this kind of thing, I think GTk is one of the most epic, impressive, ambitious C codebases in existence. Witness as non-OO C matches, rivals, and quite often beats Qt on equivalent classes/features in plain C... It's even above "just C++ style C," as they have added features like a property and signal system...

    Such a fanboy it inspired my own type system and massive core library, libgimbal, which uses a type system similar to GObject and targets game consoles like the Sega Dreamcast: https://github.com/gyrovorbis/libgimbal
