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: sidekiq_instrumentation_test.rb
    path of file: ./repos/newrelic-ruby-agent/test/multiverse/suites/sidekiq
    
    the code of the file until where you have to start completion: # This file is distributed under New Relic's license
    
  def test_running_a_job_produces_a_healthy_segment
    # NOTE: run_job itself asserts that exactly 1 segment could be found
    segment = run_job

    assert_predicate segment, :finished?
    assert_predicate segment, :record_metrics?
    assert segment.duration.is_a?(Float)
    assert segment.start_time.is_a?(Float)
    assert segment.end_time.is_a?(Float)
    assert segment.time_range.is_a?(Range)
  end
