You're allocating memory for test, but that doesn't fill it with the directory info. readdir allocates the memory for the dirent structure for you, so it isn't even necessary. Assign the return-value of readdir to test instead:

while((test = readdir(dir)) != NULL){
    printf("%s\n", test->d_name);
    // the man page says you may not free the dirent
}
