.dispatch_minitest_suites(reporter, options) ⇒ Object

Dispatch to the version-appropriate suite runner. Minitest 6 removed ::Minitest.__run; the equivalent public entry point is run_all_suites. Minitest 5.x still exposes __run.

end

.initialize_minitest_state(reporter, options) ⇒ Object

Mirror Minitest.run’s preamble: seed setup + plugin init. Without seeding Minitest.seed before dispatching suites, Minitest 5.x raises ‘TypeError: no implicit conversion of nil into Integer` from Minitest::Test.runnable_methods calling `srand(Minitest.seed)` on nil. init_plugins also needs Minitest.reporter set first because some plugins (pride) read it during init.

end

.stub_autorun! ⇒ Object

User helpers that ‘require “minitest/autorun”` install an at_exit handler calling `Minitest.run(ARGV)`. At evilution process exit ARGV still holds evilution flags (–integration, –spec, …) and Minitest’s option parser prints a misleading “invalid option” banner. Stubbing autorun before user code loads prevents the handler from ever being installed.
