      let errorSink = ExpectoIndirection.createErrorSink cts.Token
      let post =
        Codecs.Codec.log4jXML // or whichever method you use for sending to Rutta
        >> Result.map (FromNetwork >> errorSink.Post)
        >> Job.result

ErrorSink is used to assert there are no errors logged from your SUT (your whole system) while you're interacting with it.
