  # This blog post gives a good run down of the coverage criterias introduced
  # in Ruby 2.5: https://blog.bigbinary.com/2018/04/11/ruby-2-5-supports-measuring-branch-and-method-coverages.html
  # There is also a nice writeup of the different coverage criteria made in this
  # comment  https://github.com/colszowka/simplecov/pull/692#discussion_r281836176 :
  # Ruby < 2.5:
  # https://github.com/ruby/ruby/blob/v1_9_3_374/ext/coverage/coverage.c
  # traditional mode (Array)
  #
  # Ruby 2.5:
  # https://bugs.ruby-lang.org/issues/13901
  # https://github.com/ruby/ruby/blob/v2_5_3/ext/coverage/coverage.c
  # default: traditional/compatible mode (Array)
  # :lines - like traditional mode but using Hash
  # :branches
  # :methods
  # :all - same as lines + branches + methods
  #
  # Ruby >= 2.6:
  # https://bugs.ruby-lang.org/issues/15022
  # https://github.com/ruby/ruby/blob/v2_6_3/ext/coverage/coverage.c
  # default: traditional/compatible mode (Array)
  # :lines - like traditional mode but using Hash
  # :branches
  # :methods
  # :oneshot_lines - can not be combined with lines
  # :all - same as lines + branches + methods
