miniunit.h

miniunit.h is a unit testing framework for pure-C. It features a simple interface for defining unit tests, putting little in the way of the developer.

• header-file only
• no external dependencies (only uses standard C libraries)

Usage

Define MINIUNIT_MAIN before including miniunit.h on the main source file.

#define MINIUNIT_MAIN
#include "miniunit.h"

Just include miniunit.h without defining MINIUNIT_MAIN on other source files.

#include "miniunit.h"

Example

#define MINIUNIT_MAIN
#include "miniunit.h"

int main()
{
    test_case("Addition", {
        expect("1 + 1 = 2", (1 + 1) == 2);
        expect("1 + 1 + 1 = 3", (1 + 1 + 1) == 3);
    });

    test_case("Subtraction", {
        expect("1 - 1 = 0", (1 - 1) == 0);
        expect("1 - 1 - 1 = -1", (1 - 1 - 1) == -1);
        expect("example", true == false);
    });

    return 0;
}

outputs

(1) Addition
  (1-1) [Passed] 1 + 1 = 2
  (1-2) [Passed] 1 + 1 + 1 = 3
  Elapsed time 0.001451 sec
(2) Subtraction
  (2-1) [Passed] 1 - 1 = 0
  (2-2) [Passed] 1 - 1 - 1 = -1
  (2-3) [Failed] example (true == false) [main.c:15]
