module Beaker
module DSL
# These are simple patterns that appear frequently in beaker test
# code, and are provided to simplify test construction.
#
#
# It requires the class it is mixed into to provide the attribute
# `hosts` which contain the hosts to search, these should implement
# {Beaker::Host}'s interface. They, at least, must have #[]
# and #to_s available and provide an array when #[]('roles') is called.
#
module Patterns
# Execute a block selecting the hosts that match with the provided criteria
# @param [Array<Host>, Host, String, Symbol] hosts_or_filter A host role as a String or Symbol that can be
# used to search for a set of Hosts, a host name
# as a String that can be used to search for
# a set of Hosts, or a {Host}
# or Array<{Host}> to run the block against
# @param [Hash{Symbol=>String}] opts Options to alter execution.
# @option opts [Boolean] :run_in_parallel Whether to run on each host in parallel.
# @param [Block] block This method will yield to a block of code passed by the caller
#
# @return [Array<Result>, Result, nil] An array of results, a result object, or nil.
# Check {Beaker::Shared::HostManager#run_block_on} for more details on this.
