Tiny unit testing library for C language

Example

Compile executable with -D UNIT_TESTING to enable tests

#define UNIT_MAIN
#include <unit.h>

SUITE( suite name ) {
  DESCRIBE( subcase name ) {
    IT("is test behaviour") {
      WARN("use WARN_* to print failed assumptions");
      CHECK("use CHECK_* to continue execute assertions on fail");
      REQUIRE("use REQUIRE_* to skip next assertions on fail");
    }
  }
}

Features and design goals

✓ Main focus and features

• Written in Pure C: only standard libc is used
• Simplicity and tiny build-size
• No dynamic memory allocations: only static memory is used for reporting test running infrastructure.
• Single-header library: easy to integrate
• Embedded runner & pretty reporter: build self-executable test
• Disable test code: allow you to write tests for your private implementation right at the end of impl.c file
• Cross-platform: should work for Linux / macOS / Windows

✕ What you won't find here

• Cross-compiler support: no MSVC support, only clang is tested
• Multithreading and parallel test running
• Tricky test matchers design
• Fixtures, before / after or mocking
• Crash tests and signal interception
• Fuzz testing

In any case, if you have a desire, you can support and contribute! Feel free to ask me any feature you need Thank you for your interest!
