[OSGeo-Standards] Re: OGC client testing

[Jody Garnett]

I think Raj that the two are very similar. The context documents after
all do communicate what we want a client application to do. I am not
sure expect a specific map request will work for all clients; I seem
to recall some of them will check headers and decide to update
internal cache or not; especially the 3D clients I expect to make
rather different requests in response to a context document.

I am not sure we need a human for this one.

What you describe would be more useful in testing WFS-T or
GetFeatureInfo operations; I think even with these we could use a ui
testing tool and ask people to submit their application; along with a
script; for certification.
