Hello community,
I recently asked on the Users List about HTTP Comet techniques (also
known as Ajax Push).
I have already sketched an initial design and I'll start coding
briefly into my copy of the trunk.
However, and in order to help the community, I wish to give the code
so it may be included into your own test branches so eventually it can
be used by more people. In order for that to happen I need your
veteran advice on JMeter conventions and common design guidelines.
But most of all, I want to hear opinions of this selected design and
I'm more than willing to discuss and implement what's needed to get
this going.
The changes would be:
* org.apache.jmeter.protocol.http.sampler.HTTPSampler:
- Add an "Async" attribute.
- Add a "Persistent Channel" descriptor, where you can
optionally set a string identifier for the channel to use.
- Add a "Timeout" field, specifying how much time we will wait
before giving-up waiting for an assynchronous response on the
persistent channel.
* org.apache.jmeter.protocol.http.CATEGORY.CometPersistentChannel
- Create this component. This will be the backbone of Comet
testing. Data received here will be passed to the active HTTPSampler
(if it's async flag is true).
- Not sure what CATEGORY will be. For now it's on "sampler".
The usage would be something like:
* Add a CometPersistentChannel with its request filled in.
* Add some HTTPSamplers with Async turned on. Optionally configure
the Timeout and channel (if more than one available).
* Use assertions to test your logic.
I welcome any suggestions on this design and I offer myself to help
get these changes done.
Thank you for your kind time,
Rodrigo Madera
