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_method_missing.rb
    path of file: ./repos/jruby/test/jruby
    
    the code of the file until where you have to start completion: require 'test/unit'

class TestMethodMissing < Test::Unit::TestCase

    class AParent
        def method_missing *args
        end
    end

    c
    
    def test_undefined_method_missing
        assert_raise(NoMethodError){AClassWithProtectedAndPrivateMethod.new.a_missing_method}
        begin
            AClassWithProtectedAndPrivateMethod.new.a_missing_method
        rescue Exception => e
            assert(e.message =~ /undefined method/)
        end
