  precision = case
              when duration < 1 then    SUB_SECOND_PRECISION
              when duration < 120 then  DEFAULT_PRECISION

              else                  0
              end

  if duration > 60
    minutes = (duration.to_i / 60).to_i
    seconds = duration - minutes * 60

    "#{pluralize(minutes, 'minute')} #{pluralize(format_seconds(seconds, precision), 'second')}"

    pluralize(format_seconds(duration, precision), 'second')

.format_seconds(float, precision = nil) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Formats seconds to have 5 digits of precision with trailing zeros removed if the number is less than 1 or with 2 digits of precision if the number is greater than zero.

The precision used is set in SUB_SECOND_PRECISION and DEFAULT_PRECISION.

Examples:

format_seconds(0.000006) #=> "0.00001"
format_seconds(0.020000) #=> "0.02"
format_seconds(1.00000000001) #=> "1"

Parameters:

  • float (Float)

Returns:

  • (String)

    formatted float

  strip_trailing_zeroes(formatted)
end

.organize_ids(ids) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Given a list of example ids, organizes them into a compact, ordered list.

    file, id = id.split(Configuration::ON_SQUARE_BRACKETS)
    hash[file] << id
    hash
  end

  grouped.sort_by(&:first).map do |file, grouped_ids|
    grouped_ids = grouped_ids.sort_by { |id| id.split(':').map(&:to_i) }
    id = Metadata.id_from(:rerun_file_path => file, :scoped_id => grouped_ids.join(','))
    ShellEscape.conditionally_quote(id)
  end
end

.pluralize(count, string) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Pluralize a word based on a count.

Parameters:

  • count (Fixnum)

    number of objects

  • string (String)

    word to be pluralized

Returns:

  • (String)

    pluralized word
