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

class Micro::Cases::Flow::DITest < Minitest::Test
  class Add2 < Micro::Case
    attribute :number

    def call!
      number.is_a?(Numeric) ? Success(res
    
  def test_dependency_injection_using_an_inner_flow
    result = Add11.call(number: 1)

    assert_predicate(result, :success?)

    assert_equal(12, result[:number])

    # --

    result = Add22.call(number: 1)

    assert_predicate(result, :success?)

    assert_equal(23, result[:number])
  end
