While loop executing regardless of true or false state
Hi all,
I am setting up a testplan that executes reports by sending http
requests. Some of these requests take a few minutes to execute so I've
added a while loop and a cookie manager to continually access the state
of a query within any one session. The while loop checks the html being
returned - if the title is "Executing Query" (extracted from the server
response) then it continues until the correct title is returned (the
report has finished executing).
This is the basic setup:
Thread Group
HTTP Cookie Manager
Simple Controller
Http Request
Regular Expression (Reference name: Title; Regular
Expression: <title>(.*)</title>)
While Controller ("${title}" == "Executing Query")
Http Request
The While loop seems to execute regardless however I've tried placing
the same conditions in an If loop and it works fine. I've also tried
placing "Executing Query" in a user defined variable (named
Executing_Query) but the behaviour is still the same. Even when placing
2!=2 or "${Executing_Query}" != "${Executing_Query}", still the loop
executes! The title is being extracted correctly so I've run out of ideas.
Am I going about this incorrectly? Any ideas would be much appreciated!
Kim

Yes.
I had lots of problems trying to fix this, which is why I ended up
with the current implementation.
You could try using LAST instead - make sure that the sample just
before the while loop *fails* the assertion if it should not enter the
loop at all.

Re: While loop executing regardless of true or false state
Posted by Kim Wan <ki...@oracle.com>.
Thanks Seb, that helped a lot.
Using assertions is a good idea, however some instances of the report
executions will not throw up an Executing Query response and are still
valid.
What I've done is place a __regex function in the while controller:
${__regexFunction(title>(Executing Query),true,1,,false,)}
The issue that I'm now having with this is when it doesn't match, the
loop still executes once. I take it this remains from the implementation
you mentioned in October?

This is not a valid condition.
[I'm assuming you are using version 2.0.2. An earlier nightly build
did assume the condition was javascript, but this is no longer the
case - see the docs.]
The while controller requires one of the following:
- blank
- LAST
- function/variable
> Http Request
How is the value of the "title" variable going to get updated?

The If controller assumes JavaScript.

This is because the condition is not being evaluated as "false".
> Am I going about this incorrectly?
Yes, see above!
> Any ideas would be much appreciated!
It would be easier to set the condition to blank, and add an assertion
for the nested HTTP Request that fails when the title is NOT
"Executing Query" - i.e. move the Regex into the loop, and set the NOT
checkbox.
