Instance Method Details

#checked_ratio ⇒ Object

Paper basis: Schuler/Zeller 2011 (doi:10.1109/ICST.2011.32) scores the fraction of executed code that is checked by an oracle.

def checked_ratio
  executed = normalize_requirements(executed_lines || {})
  return nil if executed.empty?

  checked = per_test_checked_lines.values.flat_map do |requirements_by_path|
    normalize_requirements(requirements_by_path).to_a
  end.to_set
  (checked & executed).length.to_f / executed.length
end

#unchecked_lines ⇒ Object

Paper basis: Schuler/Zeller 2011; unchecked executed lines are reported as oracle-quality gaps rather than ordinary coverage gaps.
