What’s the corresponding replacement for " require
‘ci/reporter/rake/test_unit_loader’"in Ci_reporter2.0.0?

I am using

class HarnessTest < Watir::TestCase
require ‘ci/reporter/rake/test_unit_loader’
…
…
end
What should I need to use when I go for Minitest

class MPTEST < Minitest::Test
require (what should I use here)
…
…
end
