Hello,
In one of the recent Sandbox updates (I think it may have been when
v12 went live), the mock report that gets returned from the Sandbox's
report service went from being populated with some (static) dummy data
to being empty. This is obviously less that ideal, and I have a
request in with the folks who maintain the Sandbox environment to put
up something more useful there.
That being said, I think your best bet for exercising your report
parsing code is to actually schedule a report in the production
environment (you can do this from the
http://adwords.google.com/ web
interface or via the API), and then download the underlying XML for
the completed report from the web interface. You can then use the
local copy of this report to test your parsing logic. The XML should
be identical to a report scheduled and retrieved via the API, though
you just have to be careful to select the appropriate columns when
scheduling the report via the web interface.
