  def test_development
    assert Noodles.env.development?
    assert Noodles.env == :development
    assert Noodles.env == 'development'

    refute Noodles.env.production?

    ENV['RACK_ENV'] = "production"
    assert Noodles.env.production?
    refute Noodles.env.development?
    ENV['RACK_ENV'] = nil
  end
end```

Test Environment doesn't need Test::Rack::Methods module.
