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: with_methods_test.rb
    path of file: ./repos/u-case/test/micro/case/internal_steps
    
    the code of the file until where you have to start completion: require 'test_helper'

class Micro::Case::InternalStepsWithMethodsTest < Minitest::Test
  class SumHalf < Micro::Case
    attribute :sum

    def call!
      Success :third_sum, result: {
        sum: sum + 0.5
      }
    end
    
  def test_the_data_accumulation_through_the_then_method
    result = DoSomeCalcUsingThenWithMethods.call(a: 1, b: 2)

    assert_success_result(result, value: { sum: 10.5 })
