Kohsuke,
My main comment is that this disconnects the building of the test code
from the building of the source, which will make it easy to forget the
test code when developing the main code.
So I would really prefer that this test code be in the main source
tree (at least), and (preferably) built as part of the build. The
test itself would not run as part of the build.
