Hi All,
I am currently stuck with the following:
I have a web application that uses AJAX to display information coming
from a database in portlets (graphical representation). These portlets
each trigger a set of SQL queries in a database, and while the database
is getting the query result, an animated GIF is displayed, and
Javascript causes the browser to poll every 5 seconds or so, until the
'real' information can be displayed, at which point the polls stop.
This is an isue with JMeter, because as far as JMeter is concerned, the
request that was sent has been answered, and it moves on to the next
request.
However, what I need is essentially a loop that keeps checking what the
contents of the response is, and repeat the http request until the word
'Sarching' does not appear anymore (meaning in received data to be
displayed in the portlet).
There are a number of different portlets on each page, identified by a
unique string in the previous http response, which is used in the
'polling request' that is sent back to the server.
I have managed to get this far:
- set up a regex that extracts the unique ID for each portlet
- set up a for_each loop that goes through all of these IDs and sends
requests
- set up a regex that extracts the response from the polled request
However, the problem I have is that the while loop, which is nested
inside the for_each loop, never moves on to the second value after the
first response has finished and found the response.
Here is my test plan:
*** (various login and authentication requests)
|
@Regex called 'searching' with default value of 'NOTFINISHED'
|
*Request to move to page containing portlets (regex 'searching')
|
#For Each Controller (iterates all values for request/response above)
\
\
#While controller (loop while regex defaults to 'NOTFINISHED')
|
* Request for portlet
\
@Regex searching looking for 'searching' in response.
If not found, default value is NOTFINISHED
Everything works, except that I get stuck in the while loop after the
first portlet comes back without 'searching' - effectively having found
the information and it should then set the regex to something else.
What is wrong with this setup ? Should I be using a user-defined
variable instead of a regex ?
Thanks for your help !
