#message ⇒ Object

#omitted_frames ⇒ Object

Total backtrace frames this group's failures dropped.

def others
  @failures.reject { |failure| failure.equal?(representative) }
end

#representative ⇒ Object

The failure shown in full. We pick the one carrying the most first-party frames, because that is the one whose trace is most useful; ties break on run order so the choice is stable across runs.
