class SimpleCov::FileList

methods for calculating coverage across them etc.
An array of SimpleCov SourceFile instances with additional collection helper

Returns the count of lines that have coverage

def covered_lines
  return 0.0 if empty?
  map {|f| f.covered_lines.count }.inject(&:+)
end

Computes the coverage based upon lines covered and lines missed

def covered_percent
  return 100.0 if empty? or lines_of_code == 0
  covered_lines * 100.0 / lines_of_code
end

Computes the strength (hits / line) based upon lines covered and lines missed

def covered_strength
  return 0 if empty? or lines_of_code == 0
  map {|f| f.covered_strength * f.lines_of_code }.inject(&:+) / lines_of_code
end

Returns the overall amount of relevant lines of code across all files in this list

def lines_of_code
  covered_lines + missed_lines
end

Returns the count of lines that have been missed

def missed_lines
  return 0.0 if empty?
  map {|f| f.missed_lines.count }.inject(&:+)
end

Returns the count of lines that are not relevant for coverage

def never_lines
  return 0.0 if empty?
  map {|f| f.never_lines.count }.inject(&:+)
end

Returns the count of skipped lines

def skipped_lines
  return 0.0 if empty?
  map {|f| f.skipped_lines.count }.inject(&:+)
end
