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

class Micro::Case::StrictTest < Minitest::Test
  class Multiply < Micro::Case::Strict
    attributes
    
  def test_class_call_method
    result = Double.call(number: 2)

    assert_success_result(result, value: { number: 4 })

    result = Double.call(number: 0)

    assert_failure_result(result, type: :error, value: { message: 'number must be greater than 0' })
  end
