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: swift_ast_parser_test.rb
    path of file: ./repos/objc-dependency-visualizer/test
    
    the code of the file until where you have to start completion: require 'minitest/autorun'
require 'swift-ast-dump/swift_ast_parser'

class SwiftAstParserTest < Minitest::Test
  def test_simple_objects
    node = SwiftAST::Node.new('name')
    assert !node.nil?, 'it should be able to create simple node'
    assert_equal node.name, 'name'

    assert !SwiftAST::Pars
    
  def test_multiple_children_parsing
    source = %{
    (func_decl implicit 'anonname=0x7f85f59df460' interface type='(AppDelegate) -> (Builtin.RawPointer, inout Builtin.UnsafeValueBuffer) -> (Builtin.RawPointer, Builtin.RawPointer?)' access=internal materializeForSet_for=window\
    (parameter_list\
    (parameter "self" type='AppDelegate' interface type='AppDelegate'))\
    (parameter_list\
    (parameter "buffer" type='Builtin.RawPointer' interface type='Builtin.RawPointer')\
    (parameter "callbackStorage" type='inout Builtin.UnsafeValueBuffer' interface type='inout Builtin.UnsafeValueBuffer' mutable)))\
    }

    ast = SwiftAST::Parser.new.parse(source)
    assert_equal ast.name, 'func_decl'
    assert_equal ast.children.count, 2
  end
