Custom protocol: How to share a connection object bewteen multiple iterations

[pb...@gmx.net]

Hi,

I'm currently evaluating if we can use JMeter for our project. It seems to be almost a perfect match for the way we plan to test our system.

The only difference is that we use a custom binary protocol. The protocol is simple in a sense that it allows to connect to a server, create items, read, update, and delete them.

I've already added a custom sampler class that connects to our server and creates an item each iteration. 

I would like to reuse the connection object for multiple iterations, because in a typical scenario a client would connect once, create a couple of items, read some, and disconnect once it is done.

I would have to create the connection object before the first iteration (i.e. loop) of a thread and close it after the last iteration. What would a good way of doing this?

I thought about maybe adding a custom thread group object that knows about our protocol, creates the connection and hands it to each sampler thread, but I'm still hoping that there might be a more generic way to do this, without me having to modify core parts of JMeter (I'd rather add stuff, than modify code).

Any suggestions/directions are appreciated.

Thanks,
Rico.

You can probably use the TestListener or ThreadListener interface.
