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_rdoc_cross_reference.rb
    path of file: ./repos/truffleruby/test/mri/tests/rdoc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require_relative 'xref_test_case'

class TestRDocCrossReference < XrefTe
    
  def test_resolve_the_same_name_in_instance_and_class_method
    assert_ref @c9_a_i_foo, 'C9::A#foo'
    assert_ref @c9_a_c_bar, 'C9::A::bar'
    assert_ref @c9_b_c_foo, 'C9::B::foo'
    assert_ref @c9_b_i_bar, 'C9::B#bar'
    assert_ref @c9_b_c_foo, 'C9::B.foo'
    assert_ref @c9_a_c_bar, 'C9::B.bar'
  end
