I think these are not only some macros but every single host macros🤦.

One more thing: If monitoring is not there the tests fails fatal like this (at least locally):

Error : Class "Icinga\Module\Monitoring\Object\Host" not found
 /usr/share/icingaweb2-modules/icingadb/library/Icingadb/Compat/CompatHost.php:9
 /icingaweb2/library/Icinga/Application/ClassLoader.php:275
 /usr/share/icingaweb2-modules/icingadb/test/php/library/Icingadb/Common/MacrosTest.php:44
 

Error : Class "Icinga\Module\Monitoring\Object\Service" not found
 /usr/share/icingaweb2-modules/icingadb/library/Icingadb/Compat/CompatService.php:9
 /icingaweb2/library/Icinga/Application/ClassLoader.php:275
 /usr/share/icingaweb2-modules/icingadb/test/php/library/Icingadb/Common/MacrosTest.php:110

The if conditions in the tests don't behave as you might expect to.
