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: constant_env_test.rb
    path of file: ./repos/steep/test
    
    the code of the file until where you have to start completion: require_relative "test_helper"

class ConstantEnvTest < Minitest::Test
  include TestHelper
  include FactoryHelper

  Constan
    
  def test_module_alias
    with_constant_env({ "foo.rbs" => <<-EOS }, context: [nil, TypeName("::A")]) do |env|
module A end
module B = A
    EOS
      assert_equal TypeName("::A"), env.resolve(:A)[1]
      assert_equal TypeName("::B"), env.toplevel(:B)[1]
    end
  end
