CUnit assertion Assertion `((void *)0) != f_pCurSuite' failed

Question

My code looks like this:

#include <CUnit/CUnit.h>


int maxi(int i1, int i2)
{
    return (i1 > i2) ? i1 : i2;
}

void test_maxi(void)
{
    CU_ASSERT(maxi(0,2) == 2);
}

int main() {
    test_maxi();
    return 0;
}

I compiled it using gcc test.c -o test -lcunit on Ubuntu.

I get this error when trying to launch it:

test: TestRun.c:159: CU_assertImplementation: Assertion `((void *)0) != f_pCurSuite' failed. Aborted (core dumped)

What does it mean? I found nothing about it on the internet.

Have you checked [the example code](http://cunit.sourceforge.net/example.html)? It seems you are missing quite a lot of setup. — Some programmer dude, Jul 04 '16 at 11:50

CUnit works on test suites, you need to create before you can run the application.

A very basic way to make your test to work is like the following:

#include <CUnit/CUnit.h>
#include <CUnit/Basic.h>

int maxi(int i1, int i2)
{
    return (i1 > i2) ? i1 : i2;
}

void test_maxi(void)
{
    CU_ASSERT(maxi(0,2) == 2);
}

int main() {
    CU_initialize_registry();
    CU_pSuite suite = CU_add_suite("maxi_test", 0, 0);

    CU_add_test(suite, "maxi_fun", test_maxi);

    CU_basic_set_mode(CU_BRM_VERBOSE);
    CU_basic_run_tests();
    CU_cleanup_registry();

    return 0;
}

without all the required checks, but as Joachim Pileborg suggested in the comments, it's safer to follow the example code provided.
