hi
I'm using Jmeter for testing a local app and I found that the If
Controller doesn't behave as I expected. The expected behavior is that
it evaluates the condition once per child element, or just once?. I
dived into the code and I found that the If controller evaluates the
condition for each sampler (option B. see below) . I read the javadocs
and it's still not clear, it says
<snip>
* it will execute the set of statements
* (samplers/controllers, etc) while the 'condition' is true.
* In a programming world - this is equivalant of :
* if (condition) {
* statements ....
* }
</snip>
A.
if (condition) {
statements....
}
is different from
B.
while (condition) {
next statement
}
Personally, I'd prefer option A. rather than B. WDYT?. I attach a patch.
The patch adds an instance variable that holds the result obtained on
the first evaluation.
