class SimpleCov::FileList

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

def covered_branches

Return total count of covered branches 
def covered_branches
  return 0 if empty?
  map { |file| file.covered_branches.count }.inject(:+)
end

def covered_lines

Returns the count of lines that have coverage 
def covered_lines
  return 0.0 if empty?
  map { |f| f.covered_lines.count }.inject(:+)
end

def covered_percent

Returns:
  • (Float) - 
def covered_percent
  return 100.0 if empty? || lines_of_code.zero?
  Float(covered_lines * 100.0 / lines_of_code)
end

def covered_percentages

Returns an array with all coverage percentages
Computes the coverage based upon lines covered and lines missed for each file 
def covered_percentages
  map(&:covered_percent)
end

def covered_strength

Returns:
  • (Float) - 
def covered_strength
  return 0.0 if empty? || lines_of_code.zero?
  Float(map { |f| f.covered_strength * f.lines_of_code }.inject(:+) / lines_of_code)
end

def least_covered_file

Finds the least covered file and returns that file's name 
def least_covered_file
  min_by(&:covered_percent).filename
end

def lines_of_code

Returns the overall amount of relevant lines of code across all files in this list 
def lines_of_code
  covered_lines + missed_lines
end

def missed_branches

Return total count of covered branches 
def missed_branches
  return 0 if empty?
  map { |file| file.missed_branches.count }.inject(:+)
end

def missed_lines

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

def never_lines

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

def skipped_lines

Returns the count of skipped lines 
def skipped_lines
  return 0.0 if empty?
  map { |f| f.skipped_lines.count }.inject(:+)
end

def total_branches

Return total count of branches in all files 
def total_branches
  return 0 if empty?
  map { |file| file.total_branches.count }.inject(:+)
end
