__run(reporter, options) click to toggle source

Internal run method. Responsible for telling all Runnable sub-classes to run.

 
               # File minitest-5.15.0/lib/minitest.rb, line 160
def self.__run reporter, options
  suites = Runnable.runnables.reject { |s| s.runnable_methods.empty? }.shuffle
  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) click to toggle source

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

Minitest.after_run { p $debugging_info }

 
               # File minitest-5.15.0/lib/minitest.rb, line 84
def self.after_run &block
  @@after_run << block
end

Registers Minitest to run at process exit

    at_exit {
      next if Process.pid != pid
      @@after_run.reverse_each(&:call)
      exit exit_code || false
    }

    exit_code = Minitest.run ARGV
  } unless @@installed_at_exit

end

run(args = []) click to toggle source

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

 
               # File minitest-5.15.0/lib/minitest.rb, line 130
def self.run args = []
  self.load_plugins unless args.delete("--no-plugins") || ENV["MT_NO_PLUGINS"]

  options = process_args args

  reporter = CompositeReporter.new
  reporter << SummaryReporter.new(options[:io], options)
  reporter << ProgressReporter.new(options[:io], options)

  self.reporter = reporter # this makes it available to plugins
  self.init_plugins options
  self.reporter = nil # runnables shouldn't depend on the reporter, ever

  self.parallel_executor.start if parallel_executor.respond_to?(:start)
  reporter.start
  begin
    __run reporter, options
  rescue Interrupt
    warn "Interrupted. Exiting..."
  end
  self.parallel_executor.shutdown
  reporter.report

  reporter.passed?
end
