I agree testing both would be even nicer. Maybe you can mix your patch with mine to \
do it, calling setenv("KDE_FULL_SESSION", "1", 1) to fake the "run in KDE session" \
situation and unsetenv("KDE_FULL_SESSION") to fake the 'run outside KDE session' \
situation?

KGlobalSettingsTest fail if the test is not run in a full KDE session, see
http://my.cdash.org/testSummary.php?project=16&name=kdeui-kglobalsettingstest&date=2011-07-27
This commit changes KGlobalSettings' unit test to reflect that change. My first \
idea was to change the unit test such that it verifies the expected behaviour for \
both situations, i.e., apps run in a full KDE session and apps run in some other kind \
of session, but I could not figure out a way to do this without changing the \
KDE_FULL_SESSION environment variable before the unit test executable is run.
In the case that the signal is not expected, I reduced the kWaitForSignal timeout to \
prevent wasting too much time each time the test is run.</pre> </td>
