Module: RSpec::Signal::Grouper

Defined in:
lib/rspec/signal/grouper.rb

Overview

Collapses failures that share a fingerprint into Groups.

Ordering is deterministic: biggest group first, ties broken by the order the failures were seen, so two runs of the same suite produce byte-identical reports.
