module RCov
# A task that can verify that the RCov coverage doesn't
# drop below a certain threshold. It should be run after
# running Spec::Rake::SpecTask.
class VerifyTask < Rake::TaskLib
# Name of the task. Defaults to :verify_rcov
attr_accessor :name
# Path to the index.html file generated by RCov, which
# is the file containing the total coverage.
# Defaults to 'coverage/index.html'
attr_accessor :index_html
# Whether or not to output details. Defaults to true.
attr_accessor :verbose
# The threshold value (in percent) for coverage. If the
# actual coverage is not equal to this value, the task will raise an
# exception.
attr_accessor :threshold
# Require the threshold value be met exactly. This is the default.
