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: test_exception_handling.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/nokogiri-1.8.0/test/xslt
    
    the code of the file until where you have to start completion: require "helper"

module Nokogiri
  module XSLT
    class TestExceptionHandling < Nokogiri::TestCase
      def test_java_exception_handling
        ski
    
      def test_java_exception_handling
        skip('This test is for Java only') if Nokogiri.uses_libxml?

        xml = Nokogiri.XML(<<-EOXML)
<foo>
  <bar/>
</foo>
EOXML

        xsl = Nokogiri.XSLT(<<-EOXSL)
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="/">
    <a/>
    <b/>
  </xsl:template>
</xsl:stylesheet>
EOXSL

        begin
          xsl.transform xml
          fail('It should not get here')
        rescue RuntimeError => e
          assert_match(/Can't have more than one root/, e.to_s, 'The exception message does not contain the expected information')
        end
      end
