Hi,
   I did not look closely at your test cases per se, but I can
give you a few pointers on how to get this working (note that
I don't have a great understanding of what EWS is, actually).

First of all, I suggest the following reading material;

My recent blog post on the subject of testing D-Bus services:
http://blogs.gnome.org/tvb/2012/12/20/isolated-unit-testing-of-d-bus-services/

EDS's test case fixture code which can be found here:
http://git.gnome.org/browse/evolution-data-server/tree/tests/test-server-utils/e-test-server-utils.c
(there is a .h also, but for some reason the html view of this file is
broken, better just check it out in your EDS source code tree).

What you probably want, is your own version of e-test-server-utils.[ch]
to use for your EWS test case fixtures.

However, since I suppose EWS depends on EDS to be installed, you're
going to need to use installed EDS services.

This means that when setting up GTestDBus, for now you'll need
to call g_test_dbus_add_service_dir() to add the EDS services
which you'll need to test with EWS (ideally I think you should
be able to select specific service files to pull into your testing
environment, but currently GTestDBus only let's you pull them in as a
directory, which means your test environment will be contaminated
by whatever services are installed in ${prefix}/share/dbus-1/services,
which is 'good enough for now').

If you have your own in-tree modules to test as addressbook/calendar
backends, you'll need to set some environment variables:
 EDS_ADDRESS_BOOK_MODULES and/or EDS_CALENDAR_MODULES

These should be set to your local in-tree modules, for example:
 EDS_ADDRESS_BOOK_MODULES=${top_builddir}/ews/addressbook-module/.libs

See specifically the function setup_environment() function in the
EDS test case fixture code, since you are testing with an installed
EDS in the environment, you'll probably need to point
GSETTINGS_SCHEMA_DIR to the real installed schema directory in
the given prefix (otherwise EDS will complain, because EDS needs
it's own schemas to startup properly).

Note that what you're trying to do is a little different from EDS,
since EDS is pretty self-contained and does not depend on external
installed services to run, while EWS requires the installed copy
of EDS, this will present a challenge for you.

Hope this was helpful, good luck ;-)

Cheers,
       -Tristan
