Basically what I did was create a small disk, create one partition

it and format it with a filesystem (without any LVM). That is one
of the things you were adding support for, but it is not limited to
Windows Bitlocker setup, it can just as well be a custom setup when
installing any Linux distro.
Even after quite a bit of fighting, rebuilding the appliance and so
on I did not manage for it to show up in the list-filesystems or
even do a cryptsetup-open on the partition even though it uses an
appliance built from git master with the patches applied. But I'm
quite sure I could've done something wrong, so if that works for
you, that's enough.
There's something in the test suite that already does this, so
$ make && make -C test-data check
should produce test-data/phony-guests/fedora-luks.img (see
test-data/phony-guests/make-fedora-img.pl for how).
This image can be opened:
$ guestfish --ro -a test-data/phony-guests/fedora-luks.img -i
Enter key or passphrase ("/dev/sda2"): FEDORA

However ...
Still, since you cannot do the test for Bitlocker, my idea was that
you could make the test for non-lvm parition encrypted by LUKS as
that would check some of the other code.
... cryptsetup cannot create a new BitLocker disk, which is rather
unfortunate. I created a BitLocker disk using Windows, and I'll
privately send you a link, but because of the cryptsetup problem
there's no way to automate this kind of test.
