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: process_search_recommendations_test.rb
    path of file: ./repos/workarea/core/test/workers/workarea
    
    the code of the file until where you have to start completion: require 'test_helper'

module Workarea
  class ProcessSearchRecommendationsTest < Workarea::TestCase
    def test_processing_user_activity
      Metrics::User.create!(viewed: { search_ids: %w(foo bar) })
      2.times { Metrics::User.create!(v
    
    def test_within_expiration
      Metrics::User.create!(viewed: { search_ids: %w(1 2) })
      travel_to((Workarea.config.recommendation_expiration + 1.day).from_now)
      2.times { Metrics::User.create!(viewed: { search_ids: %w(1 3) }) }

      ProcessSearchRecommendations.new.perform

      predictor = Recommendation::SearchPredictor.new
      assert_equal(%w(3), predictor.similarities_for('1'))
    end
