object. C<sub> is a string containing a fully-qualified subroutine name.
C<pageName> is the name of the page subroutine to run (may be C<undef> for
sub strings. C<options> is a hash reference of options with keys outlined
below.

used for testing.
Optionally adds a filename to the end.

Returns the full path to the WebGUI root directory, usually /data/WebGUI.

#----------------------------------------------------------------------------
=head2 session ( )
Returns the WebGUI::Session object that was created by the test. This session object
will automatically be destroyed if the test finishes without dying.
The logger for this session has been overridden so that you can test
that WebGUI is logging errors. That means that errors will not be put into
your webgui.log file (or whereever log.conf says to put it). This will probably
be moved into a utility sub so that the interception can be enabled, and then
disabled.
=cut
sub session {
return our $SESSION;
}
#----------------------------------------------------------------------------
=head2 webguiBirthday ( )
This constant is used in several tests, so it's reproduced here so it can
be found easy. This is the epoch date when WebGUI was released.
=cut

#----------------------------------------------------------------------------
=head2 getSmokeLDAPProps ( )

#----------------------------------------------------------------------------
=head2 cleanupAdminInbox ( )
Push a list of Asset objects onto the stack of assets to be automatically purged
at the end of the test. This will also clean-up all version tags associated
with the Asset.
This is a class method.
=cut

#----------------------------------------------------------------------------
=head2 cleanupGuard ( $object, $class => $ident )
Pass in a list of objects or pairs of classes and identifiers, and
it will return a guard object for cleaning them up. When the guard
object goes out of scope, it will automatically clean up all of the
passed in objects. Objects will be destroyed in the order they
were passed in. Currently able to destroy:
WebGUI::AdSpace
WebGUI::Asset
WebGUI::Group
WebGUI::Session
WebGUI::Storage
WebGUI::User
WebGUI::VersionTag
WebGUI::Workflow
WebGUI::Shop::Cart
WebGUI::Shop::ShipDriver
WebGUI::Shop::PayDriver
WebGUI::Shop::Transaction
WebGUI::Shop::Vendor
WebGUI::Shop::AddressBook
WebGUI::DatabaseLink
