# Checks for long examples.
#
# A long example is usually more difficult to understand. Consider
# extracting out some behavior, e.g. with a `let` block, or a helper
# method.
#
# @example
# # bad
# it do
# service = described_class.new
# more_setup
# more_setup
# result = service.call
# expect(result).to be(true)
# end
#
# # good
# it do
# service = described_class.new
# result = service.call
# expect(result).to be(true)
# end
#
# You can set literals you want to fold with `CountAsOne`.
# Available are: 'array', 'hash', and 'heredoc'. Each literal
# will be counted as one line regardless of its actual size.
#
# @example CountAsOne: ['array', 'heredoc']
#
# it do
# array = [ # +1
# 1,
# 2
# ]
#
# hash = { # +3
# key: 'value'
# }
#
# msg = <<~HEREDOC # +1
# Heredoc
# content.
# HEREDOC
