Subject: [PATCH] tests: Add basic tests for gobject-query utility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At the moment these tests basically just ensure that the program’s
compiled properly and doesn’t crash on startup. They don’t check
functionality very deeply.

But they’re a start.
