You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: superselector_test.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/sass-3.4.24/test/sass
    
    the code of the file until where you have to start completion: #!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../test_helper'

class SuperselectorTest < MiniTest::Test
  def test_superselec
    
  def test_matches_can_be_subselector
    %w[matches -moz-any].each do |name|
      assert_superselector '.foo', ":#{name}(.foo.bar)"
      assert_superselector '.foo.bar', ":#{name}(.foo.bar.baz)"
      assert_superselector '.foo', ":#{name}(.foo.bar, .foo.baz)"
    end
  end
