def coverage_lines_by_file(path = DEFAULT_COVERAGE_REPORT_PATH)
  return {} unless File.exist?(path)

  coverage = Hash.new { |hash, key| hash[key] = [] }
  JSON.parse(File.read(path)).each_value do |result|
    result.fetch("coverage", {}).each do |file, file_coverage|
      coverage[normalize_path(file)].concat(covered_lines(file_coverage))
    end
  end

  coverage.transform_values(&:uniq).transform_values(&:sort)
end

#durations_by_test(path = DEFAULT_PER_TEST_COVERAGE_REPORT_PATH) ⇒ Hash[String, Float]

Parameters:

  • (String)

Returns:

  • (Hash[String, Float])
