You shouldn't add external tests to bb-hosts. You add them to etc/bb-bbexttab.

$ head -30 etc/bb-bbexttab
# bb-bbexttab: configuration file for launching external scripts
#
# Format:
#
# host: misc settings : external scripts list
# localhost: misc settings : external scripts list
# : misc settings : external scripts list
#
# host can be FQDN (fully qualified domain name) or
# just a plain hostname but it is preferred that you
# use a FQDN.
# localhost: using this specifies that the scripts
# specified on the line are to be launched on all clients
#
# The same host can be specified on multiple lines to aid readability
#
# Misc settings field is unimplemented ...
# For future use...
#
# You can override the default sleep between cycles
# by addding a time qualifier to the script:
# e.g.: localhost: script1;600
# **NOTE** The sleep delimiter in BBEXT of bbdef.sh was
# ':' (script1:600) but here it is ';'
# in order to keep the same format as the
# other bb-*tab files (the : is used to delimit
# file entry fields in all bb-*tab files) .
# The time qualifier is specified in SECONDS
