Minitest 6: test feistier!

on YouTube ↗38m

" summary

Minitest 6 promises concrete upgrades: a new result class with safe serialization to allow worker‑based distributed runs, stronger parallelism with an option to be parallel by default, a CLI runner and better Rake integration, tightened assertions (assert_equal(nil) raises), cleaned global namespace for spec expectations, improved mocks/stubs, and lighter reporters. Benchmarks converted suites show ~30% slower in an RSpec translation; current stable is 5.11.x with 5.12 turning on deprecations.
