Re: Fw: [wsbpel-implement]
Portability and Interoperability TestingLink
Hi Diane,
I was trying to post the following on
the oasis list, but something's wrong with the smtp server so i couldn't.
Can it please get posted somehow ? This
e-mail address is not the one I use in the TC so I can't post from here.
---------------------------
Hi everyone,
Ron, thanks for kicking things up around
here again :)
First some background: We started out
wanting to do some initial interop/portability trials by excercising parts
of the
spec, starting with ones that we all
are on the same page on, and moving
to ones that are more closely related
to the issues. This is what led to
the initial set of scenarios that we
put up last year. We want to actually run stuff, and for that
we have a starting set of scenarios ready to run and taken mainly from
the spec itself. The setup is to be informal, with an open forum on how
things should run/how they actually ran on the different engines
being experimented with.
I think this is the right level for
this stage in BPEL's life (although
it would help if people would come forward
with engines to actually move
forward). It helps us share/run interacting
BPELs, clarify issues being
discussed on the main list, and addresses
any ambiguities that may come
up during execution that we can clarify
in the updated specification.
A full testing/compliance suite would
be desirable for BPEL; however,
this is not the right time for it and
it's not in the scope of the TC
(building compliance tools). Perhaps
something could go on in parallel,
maybe in the WS-I, after the spec is
finalized and released so that
people refer to a full version. I am
strongly against doing this here.
Sadly, we didn't even get enough people
to join to do the above, simple, test scenarios and start up the basic
discussions that would lead to an
understanding of what it would take
to have portability/interop in BPEL.
I would just like to see people moving
away from bullet lists and
wanting to draw up more examples and
discussing how things *should* run,
to actually openly and collaboratively
running stuff, talking about the
results, the assumptions, the assumptions
proved wrong. This is where we
want to go, and this is the right forum
to do it in.
Rania

fyi - at last some activity on implementations.
I guess Sun has their code ready.
I don't think validation tools or certification
are in scope for TC though.
I'll respond on the list that I'm glad
to see renewed interest and point to the call that's planned for Mar. 1.
Feel free to comment on the list if
you wish.

RE: [wsbpel-implement] Portability
and Interoperability Testing
I agree that this needs to happen in order for BPEL to gain acceptance
in
the industry. Here are some of objectives that spring to mind:
1. Provide the tools for implementers to validate their implementations,
this could include:
1.1. Defining a set of BPEL processes/use cases that will collectively
cover
the functionality of the entire BPEL specification. These test cases should
be delivered in conjunction with new the release of new BPEL specifications.
1.2. Define the expected results when running the BPEL processes above,
which could be done by either supplying the message contents that are
involved and their flow, or providing actual implementations on a central
site so that the test processes can be run with different input.
1.3. Either providing a set of WSDL definitions for the web services that
will take part, or even better, provide actual implementations at a central
site so that there will be no misinterpretations when implementing the
web
services involved in the business process.
2. Provide some ways for, for lack of a better work, certification. This
of
course implies that some independent entity is available to do the
certification. While certification is a huge effort by itself, without
it,
there will be no way to tell if a given implementation is in fact compliant.
3. Interoperability. This would imply cooperation on behalf of all, or
a
large majority of, BPEL implementers. How do we get implementers to ensure
portability amongst themselves?

Kristofer

BPEL implementors:
I've been giving some thought lately to the issues of testing
or
demonstrating compliance to the WS-BPEL specification. As we have
discussed in the past this really falls into two categories: portability
and interoperability.
Historically there have been several approaches to testing
such
compliance. Our situation is complicated by dependencies on
implementation-specific messaging infrastructure, so we have some other
issues to deal with before we get to the main event. What approaches do
you, the implementors of BPEL, see as the most likely to demonstrate
BPEL compliance, portability, and (reasonable) interoperability? Should
we start trying to spin up an effort (perhaps external) to do this?
I believe that doing nothing in this domain will do a lot
of harm to
BPEL. Are we at the right stage in BPEL's life to worry about this? Or
has someone started addressing this issue already?
Cheers,
-Ron
