[infinispan-dev] HotRod client TCK

[Radim Vansa]

Since these tests use real server(s), many of them test not only the 
client behaviour (generating correct commands according to the 
protocol), but server, too. While this is practical (we need to test 
server somehow, too), there's nothing all the tests across languages 
will have physically in common and all comparison is prone to human error.

If we want to test various implementations of the client, maybe it would 
make sense to give the clients a fake server that will have just a 
scenario of expected commands to receive and pre-defined responses. We 
could use audit log to generate such scenario based on the actual Java 
tests.

But then we'd have to test the actual behaviour on server, and we'd need 
a way to issue the commands.

Just my 2c
