退出“；如果；在“a”中；而"；vbscriptqtp中的循环

我遇到了退出while循环的问题 我试过使用break，Exit do

自动测试用例的算法如下

while true
do some tasks
    if total >200 then 
       do some tasks 
       and 
       exit out of while loop if this condition reaches
    End if
wend

---

如果唯一的退出点位于

total>200

do
    do_some_tasks
    if total > 200 then
        do_total_related_tasks
    end if 
loop until total > 200

这可以简化为

do
    do_some_tasks
loop until total > 200
do_total_related_tasks

对于更通用的多个退出点，最快的选项是

exit do

do
    do_some_tasks
    if total > 200 then
        do_total_related_tasks
        exit do
    end if 
    other_tasks
loop while true

或者，对于更一般的解决方案，使用变量

keepTesting = true
do
    do_some_always_tasks
    ' start to test conditions
    if keepTesting then if total > 200 then 
        do_total_related_tasks
        keepTesting = false
    end if 
    if keepTesting then if other_exit_condition then
        .....
        keepTesting = false
    end if 
    .....
loop while keepTesting

---

或者根据实际问题的任何其他构造。

如果唯一的退出点位于

总计>200

    do_some_tasks
    if total > 200 then
