MinUnit

及其简单的 C 语言测试框架，主页：http://www.jera.com/techinfo/jtns/jtn002.html

minunit.h:

#define mu_assert(message, test) do { if (!(test)) return message; } while (0)
#define mu_run_test(test) do { char *message = test(); tests_run++; \
                                if (message) return message; } while (0)
extern int tests_run;

例子

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

int tests_run = 0;

int foo = 7;
int bar = 4;

static char * test_foo() {
    mu_assert("error, foo != 7", foo == 7);
    return 0;
}

static char * test_bar() {
    mu_assert("error, bar != 5", bar == 5);
    return 0;
}

static char * all_tests() {
    mu_run_test(test_foo);
    mu_run_test(test_bar);
    return 0;
}

int main(int argc, char **argv) {
    char *result = all_tests();
    if (result != 0) {
        printf("%s\n", result);
    }
    else {
        printf("ALL TESTS PASSED\n");
    }
    printf("Tests run: %d\n", tests_run);

    return result != 0;
}
