segmentation fault - jetlongjump ?

[ya...@infiswift.com]

Hello,

I am new to Unity testing framework. I just downloaded the code from github and trying to run a simple program:

// file test1.c

#include <stdio.h>

#include <stdlib.h>

#include "unity.h"

int main()

{

    int a=2;

    TEST_ASSERT_TRUE(0);  //Gives segmentation fault TEST_ASSERT_TRUE(1); works (no fault

    printf("Hello this is test1.\n");

}

I compile using

gcc -c test1.c

gcc -c unity.c

gcc test1.o unity.o -o test1

Thanks

Yash

Hi!

You're getting a segfault because the assertions use longjmp to immediately jump out of the test. This requires a properly formed setjmp ahead of time. This (and other accounting) are handled by the macros UNITY_BEGIN() and UNITY_END(). You need to call those before and after any tests. In addition, it's best to wrap your tests themselves in RUN_TEST macros. 

Your test would then look something like this:

// file test1.c

#include <stdio.h>

#include <stdlib.h>

#include "unity.h"

void test_firstTest(void)

{

    int a=2;

    TEST_ASSERT_TRUE(0);  //Gives segmentation fault TEST_ASSERT_TRUE(1); works (no fault

    printf("Hello this is test1.\n");

}

int main(void)

{

    UNITY_BEGIN();

    RUN_TEST(test_firstTest, 5);

    return UNITY_END();

}

You can find more information about this in the documentation folder. In particular, check out the file UnityGettingStartedGuide.md

Best of luck!
