| re the mockup comments, see mock objects in Wikipedia (http://en.wikipedia.org/wiki/Mock_object). That certainly is what we are looking for. I'l have to introduce a definition similar to what is in Wikipedia because I don't think we want to be referencing Wikipedia directly.

It also strikes me that it might also be good to draw a distinction between inter- and intra-enterprise or ecosystem and enterprise testing.

Happy New Years back atcha.
Thanks for your quick comments. Here are some thoughts:
re mockup, I understand your concern and have some of it myself.
Traditionally, mockups were for visual effects and less functional,
although I believe car mockups are used for wind tunnel testing. I
have seen use of mockup in service discussions as something more on
the functional end. This may be a case of evolving terminology or
just sloppy use. It deserves more attention.
The write-up is ecosystem heavy, and I may be overreacting to a lot
of the SOA literature that is sealed in the enterprise like my
swimming pool of sea water. I want an ecosystem emphasis but it
must also be relevant to the enterprise. That will get attention
too.
On the question of continuous testing vs. waterfall, I'll need to
reread because I thought I emphasized this as a major point. It was
certainly intended.
I'll let this sit a couple days, get a few more comments and then
start to revise.
Thanks again,
Ken

Ken:
From a quick read I have three concerns. But, first Happy New Year, and
this is a good start. Now:
First, is your use of the term mock up. In aircraft, cars, and
industrial products, mockups are used as part of an early evaluation of
the conceptual design of a product and does not have great fidelity with
the actual product. And typically, mockups are of the product not the
context. If I remember correctly, in modeling, a simulation of the
"test" environment is termed the simulandum (sp?). The term mockup as
you use it in this section, "jars my eye teeth."
Second, this section reeks of ecosystem SOA testing only. While that is
unique and new, I suspect that there will be many more business or
organizational critical enterprise SOAs initially, than ecosystem SOAs
and there is plenty of testing of services with respect to the business
processes that will need to be performed, which is also unique and new.
Third, this section implies a waterfall development process. I think
that in service/composite application lifecycle of the future, testing
will continue through the entire lifecycle, not just during
implementation. This didn't jump out at me, though it may be buried in
the text.
Just my two cents to try to help.
Bob

OK, folks, here it is.
I'm not completely satisfied with the organization and I'll need some
help in defining models, but I think I have covered most of the
territory I wanted. I took into account comments from Frank, Rex, and
Bob, and I believe your comments and concerns have been addressed to
what I felt was a consistent level of detail appropriate for the RA.
(There are several mentions of further detail being out of scope.)
I'm sure you'll all let me know if I missed something.
Ken
