testdriver1.c

1、编写测试驱动 2、设计相应的黑盒测试用例

//测试编码

#include <stdio.h>
#include <stdlib.h>

FILE *itest,*otest;

void testdriver1(FILE *itest)
{
short           father[512];
unsigned short  code[256], heap_length;
unsigned long   compress_charcount, file_size, heap[257];
unsigned char   code_length[256];
long            frequency_count[512];

FILE            *ifile, *ofile;

ifile=itest;

get_frequency_count ();
build_initial_heap ();
reheap (heap_entry);
build_code_tree ();
generate_code_table ();
compress_image ();
compression_report ();

otest=ofile;
return(otest);
}
