  It defines common `vc` specific functions on top of `Model` implementation.

docstr: Generic test run for `vc` models used by `Trainer`.
  
  You can override this for a different behaviour.
  
  Args:
      assets (dict): A dict of training assets. For `vc` models, it must include `{'audio_processor': ap}`.
  
  Returns:
      Tuple[Dict, Dict]: Test figures and audios to be projected to Tensorboard.
