Mint Unit

A minimal unit testing framework for C code. Mint Unit has a TAP like output syntax, but unlike TAP implementations it stops on the first failing test following the fail-fast fail-hard idea of being forced to fix tests rather than observe broken ones. This code was influenced by a minimal test framework published in Jera Tech Notes.

Usage

To use Mint Unit, include mintunit.h header file in your testing application and start writing tests. Suites should return NULL on successful test. The test suites are executed using mt_run_test(<name>). Sample usage of mint unit can be seen below:

#include <stdio.h>
#include "mintunit.h"

static char *
test_foo(void)
{
	 mt_assert("Test foo function", foo(5) == 5);
	 mt_is_null("Test bar function returns NULL", bar(5));
	 return NULL;
}

static char *
run_tests(void)
{
	mt_init(1);
	mt_run_test("Testing foo", test_foo);
	return NULL;
}

int
main(int argc, char **argv)
{
	char *test_result = run_tests();
	if (!test_result)
		printf("\n# All tests passed\n");
	printf("# Test Suites run: %d\n# Unit Tests run : %d\n", tests_run, units_run);

	return test_result == NULL ? 0 : 1;
}
