怪事！！

我按照Winrunner的中文用户说明学习，在用Sample applications-->flight 4A做练习时，检查其票数乘以其单价是否等于总价时，结果没有通过；而我将语句 if(tickets*price == total)修改成if(tickets*price < total)时，却能通过。请问各位高手，我是哪里出了问题。我录制的脚如下：（我之前有做过同样的练习，结果是成功的，后来被我不小心删除了，等我再做时就老是通不过了，不知道哪里出了问题？我用的是7.6版本的）
# Fax Order No. 3
set_window ("Fax Order No. 3", 2);
menu_select_item ("File;Open Order...");

# Open Order
set_window ("Open Order", 0);
button_set ("Order No.", ON);
edit_set ("Edit_1", "3");
button_press ("OK");

# Fax Order No. 3
set_window ("Fax Order No. 3", 3);
menu_select_item ("File;Fax Order...");

# Fax Order No. 3_1
set_window("Fax Order No. 3_1", 1);
static_get_text("# Tickets:(static)",tickets);
static_get_text("Ticket Price:(static)",price);
static_get_text("Total:(static)",total);

if(tickets*price == total)
   tl_step("total",0,"total is correct.");
else
   tl_step("total",1,"total is incorrect.");

set_window ("Fax Order No. 3_1", 2);
button_press ("Cancel");

tickets是int，但price的值是“$123”，就是因为钱前面的单位造成的，你应该首先将字符串前面的金钱单位去掉之后再作比较就好了，使用函数substr()，修改如下：
# Fax Order No. 3
   set_window ("Fax Order No. 3", 2);
   menu_select_item ("File;Open Order...");

# Open Order
   set_window ("Open Order", 0);
   button_set ("Order No.", ON);
   edit_set ("Edit_1", "3");
   button_press ("OK");

# Fax Order No. 3
   set_window ("Fax Order No. 3", 3);
   menu_select_item ("File;Fax Order...");

# Fax Order No. 3_1
set_window("Fax Order No. 3_1", 1);
static_get_text("# Tickets:(static)",tickets);
static_get_text("Ticket Price:(static)",price);
static_get_text("Total:(static)",total);

#add
price=substr(price,2);
total=substr(total,2);
#add end


   if(tickets*price == total)
      tl_step("total",0,"total is correct.");
   else
      tl_step("total",1,"total is incorrect.");

   set_window ("Fax Order No. 3_1", 2);
   button_press ("Cancel");

谢谢wenlaqing给我的解答，可是我按照上面的修改还是没有通过。price的单位在哪里修改啊？脚本里没有体现出来

但是我昨天晚上是实现了的阿，怎么会了，像这样的情况你可以在变量赋了值后用report_msg()函数来查看一下tickets,price和total它们的值就可以看出问题，相信这样能够解决。
不知道你的代码还有什么问题，继续讨论。

# Fax Order No. 3_1
set_window("Fax Order No. 3_1", 1);
static_get_text("# Tickets:(static)",tickets);
static_get_text("Ticket Price:(static)",price);
static_get_text("Total:(static)",total);

你取值取错了， static_get_text是返回静态文本对象的内容

谢谢各位的解答，已经成功了，是我取值错了。不过还有个问题：取值错了为什么改成小于又能通过呢？

楼主, 把你成功的完整CODE 贴出来吧, 大家共享一下.

欣蕊发表于 2006-8-16 19:55:22

成功代碼如下，我只是改變了取值而已：
# Fax Order No. 3
   set_window ("Fax Order No. 3", 2);
   menu_select_item ("File;Open Order...");

# Open Order
   set_window ("Open Order", 0);
   button_set ("Order No.", ON);
   edit_set ("Edit_1", "3");
   button_press ("OK");

# Fax Order No. 3
   set_window ("Fax Order No. 3", 3);
   menu_select_item ("File;Fax Order...");

# Fax Order No. 3_1
set_window("Fax Order No. 3_1", 1);
edit_get_text("# Tickets:",tickets);
edit_get_text("Ticket Price:",price);
edit_get_text("Total:",total);


   if(tickets*price == total)
      tl_step("total",0,"total is correct.");
   else
      tl_step("total",1,"total is incorrect.");

   set_window ("Fax Order No. 3_1", 2);
   button_press ("Cancel");

原来这样，我昨天用的是obj_get_text()，学习中！你用report_msg就可以看到变量所取的值，就知道为什么改为<=就对了的原因
