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: unescape_test.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/escape_utils-1.1.1/test/html
    
    the code of the file until where you have to start completion: # encoding: utf-8
require File.expand_path("../../helper", __FILE__)

class HtmlUnescapeTest < Minitest::Test
  def test_basic_html
    assert_equal "<some_tag/>", EscapeUtils.unescape_html("&lt;some_tag&#47;&gt;")
  end

  def test_double_quotes
    asser
    
    def test_input_must_be_utf8_or_ascii
      escaped = EscapeUtils.escape_html("<b>Bourbon & Branch</b>")

      escaped.force_encoding 'ISO-8859-1'
      assert_raises Encoding::CompatibilityError do
        EscapeUtils.unescape_html(escaped)
      end

      escaped.force_encoding 'UTF-8'
      begin
        EscapeUtils.unescape_html(escaped)
      rescue Encoding::CompatibilityError => e
        assert_nil e, "#{e.class.name} raised, expected not to"
      end
