[TynesideLUG] Test driven development

[Ian Bruntlett]

Hi,

I've just used test driven development in C! Here is a function that
removes preceding whitespace from a string..

#include <stdio.h>
#include <string.h>
#include <ctype.h>

#define TEST_MAX (100)
void ltrimcpy(char *dest, char *src)
{
  char *first_ok;
  for (first_ok=src;
       isspace(*first_ok);
       ++first_ok)
  ;
  strcpy(dest,first_ok); // possibly use strncpy?
}

void test_ltrimcpy(char *test_argument)
{
  char test_result[TEST_MAX];
  ltrimcpy(test_result, test_argument);
  printf("argument : '%s' result : '%s'\n", test_argument, test_result);
}

int main(void)
{
  test_ltrimcpy("  Hello ");
  test_ltrimcpy("Hello ");
  test_ltrimcpy("");
  return 0;
}
