When bisect isn't working properly get a print out of files in order (--require ./bisect_formatter.rb --format BisectFormatter)

bisect_formatter.rb

class BisectFormatter < RSpec::Core::Formatters::ProgressFormatter
  RSpec::Core::Formatters.register self, :example_started, :example_passed, :example_pending, :example_failed, :start_dump

  def initialize(output)
    @output = output
    @files_processed = {}
  end

  def example_started(notification)
    return if @files_processed.key?(notification.example.file_path)

    @files_processed[notification.example.file_path] = true
    @output.print notification.example.file_path
    @output.print "\n"
  end
end
