Our main goal is to show that if you build a package under our tool (using
./ourTool dpkg-buildpackage -uc -us -b):
1) the package will always build the same way (assuming same environment,
compiler version, libraries, etc). We verify this using reprotest +
continuous integration system.
2) The reviewers of our last publication submission were concerned about
"correctness". That is, does our generated deb file have equivalent
semantics to that of a deb file built without our tool. Basically, they're
concerned out dynamic manipulation leads to an incorrect build. So we want
to run the unit tests for a few packages (a dozen or so) to show that the
package still works as intended after going through our tool.

That's why I'm trying to identify some packages with tests to run.
