Some system tests assume dig's default setings are in effect. While these defaults may only be silently overridden (because of specific options set in /etc/resolv.conf) for BIND releases using liblwres for parsing /etc/resolv.conf (i.e. BIND 9.11 and older), it is arguably prudent to make sure that tests relying on specific +timeout and +tries settings specify these explicitly in their dig invocations, in order to prevent test failures from being triggered by any potential changes to current defaults.
