Hello there,
First of all, congratulations to the creators of this nice tool.
Outstanding!
Using JMeter, I'm testing a web server that uses Ajax Push, and this
is proving to be kind of tricky to do with JMeter.
Let me set up an example: a server that eats fruits. You send a
"regular" HTTP request and you request it to eat a fruit, using a
serialized JSON request object representing the parameters of the
fruit. As the server eats the requests, he will use Ajax Push to send
the results through a unique channel for the client.
Of course this is a silly example that can be implemented using
numerous trivial methods, but my intent is to demonstrate my case with
a simple analogy.
So let's look at a normal day's life of our beloved server:
1) Server: Ready for some juicy action...
2) Client -> Server: HTTP Request: POST
/create/persistent/channel/and/keep/this/thing/open/will/ya
(the server keeps the connection open and will send some stuff
here once the fruit requests come... basic Comet stuff)
3) Client -> Server: HTTP Request: GET
/actions/eat/some?request={json_stuff_here_about_the_fruit_to_eat}
Server Response: OK Dude, I'll eat that and tell you when I'm done.
This connection is then closed.
4) Server -> Client: <script>process({json_results_object_here});</script>
The result is sent to the appropriate persistent connection.
Since the server has devoured the fruit that was requested, he
sends a response to the persistent connection.
Again, basic Comet stuff.
So from this typical Comet dialog we can see that it gets tricky to
test with conventional JMeter components.
So, after this lengthy introduction comes a simple question: Any
improvements/tests/successes with Ajax Push testing with JMeter?
If not, I'm willing to help you create the needed components for this
to happen. Of course, if nothing already is being made.
Thank you for your time,
Rodrigo Madera
