main.rb:

gem 'minitest', '5.0.2'
require 'minitest/autorun'

$require = Kernel.method(:require)
$location = $require.source_location
$params = $require.parameters

class T < Minitest::Test
  def test_wat
    assert_equal $require, Kernel.method(:require)
    assert_equal $location, Kernel.method(:require).source_location
    assert_equal $params, Kernel.method(:require).parameters
  end
end

Result:

$ ruby -v main.rb

Huh, that's a weird one. Confirmed on master, and I have no idea what's up.

Simpler reproduction. It just seems that it's losing parameters for calls past the first:

r = Kernel.method(:require)
p r.parameters
p r.parameters

Odd indeed. That makes more sense than "during Minitest run" at least.
