如何結合gdb和gcov進行白盒測試?主要有兩個階段： 1.編譯程序，執行gdb調試腳本。 在編譯程序的時候加上-fprofile-arcs -ftest-coverage參數。所以這里運行 gcc
如何結合gdb和gcov進行白盒測試?主要有兩個階段：
1.編譯程序，執行gdb調試腳本。
在編譯程序的時候加上-fprofile-arcs -ftest-coverage參數。所以這里運行
gcc -fprofile-arcs -ftest-coverage -g -o calnumber calnumber.c
gdb的命令參數-x可以從文件讀出gdb調試命令再執行。運行
gdb -x calnumber.gdb > calnumber.res
下面是gdb腳本的輸出：
$cat calnumber.res

Test Case 1
Breakpoint 1 at 0x401083: file calnumber.c, line 4.
Breakpoint 1, main () at calnumber.c:4
4 {
Breakpoint 2 at 0x401096: file calnumber.c, line 9.
Breakpoint 2, main () at calnumber.c:9
9 for(i = 0; i <= number; i++)
"check number == 8" $1 = 1
"check sum == 0" $2 = 1
"set number = 4" $3 = 4
Breakpoint 3 at 0x4010c2: file calnumber.c, line 14.
Breakpoint 3, main () at calnumber.c:14
14 if(sum != 36)
"set sum = 10" $4 = 10
Breakpoint 4 at 0x401121: file calnumber.c, line 24.
Breakpoint 4, main () at calnumber.c:24
24 if(quit) printf("Finish!\n");
"check quit == 0" $5 = 1
"check i == 5" $6 = 1
"check sum == 10" $7 = 1
sum = 10
Program exited normally.

"check i == 9" $8 = 1
