  parallel, serial = suites.partition { |s| s.test_order == :parallel }

  # If we run the parallel tests before the serial tests, the parallel tests
  # could run in parallel with the serial tests. This would be bad because
  # the serial tests won't lock around Reporter#record. Run the serial tests
  # first, so that after they complete, the parallel tests will lock when
  # recording results.
  serial.map { |suite| suite.run reporter, options } +
    parallel.map { |suite| suite.run reporter, options }
end

.after_run(&block) ⇒ Object

A simple hook allowing you to run a block of code after everything is done running. Eg:

Minitest.after_run { p $debugging_info }

.run(args = []) ⇒ Object

This is the top-level run method. Everything starts from here. It tells each Runnable sub-class to run, and each of those are responsible for doing whatever they do.

The overall structure of a run looks like this:

Minitest.autorun
  Minitest.run(args)
    Minitest.__run(reporter, options)
      Runnable.runnables.each
        runnable.run(reporter, options)
          self.runnable_methods.each
            self.run_one_method(self, runnable_method, reporter)
              Minitest.run_one_method(klass, runnable_method)
                klass.new(runnable_method).run
