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_gem_resolver_index_specification.rb
    path of file: ./repos/ruby-packer/ruby/test/rubygems
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require 'rubygems/test_case'
require 'rubygems/available_set'

class TestGemResolverIndexSpecification < Gem::TestCase

  def test_initialize
    set     = Gem::Resolver::IndexSet.new
    source  = Gem::Source.new @gem_repo
    version = Gem::Version.new '3.0.3'

    spec = Gem::Resolver::IndexSpecification.new(
      set, 'ra
    
  def test_spec_local
    a_2_p = util_spec 'a', 2 do |s|
      s.platform = Gem::Platform.local
    end

    Gem::Package.build a_2_p

    source = Gem::Source::Local.new
    set = Gem::Resolver::InstallerSet.new :local
    set.always_install << a_2_p

    i_spec = Gem::Resolver::IndexSpecification.new \
      set, 'a', v(2), source, Gem::Platform.local

    spec = i_spec.spec

    assert_equal a_2_p.full_name, spec.full_name
  end
