[Qemu-devel] [PATCH 26/29] Introduce QInt unit-tests

[Luiz Capitulino <lcapitulino@redhat.com>]

This suite contains tests to assure that QInt API works as expected.

To execute it you should have check installed and build QEMU with
check support enabled (--enable-check-utests) and then run:

$ ./check-qint
