"""test_feature_extractors_functional.py -- functional tests for feature extractors

This module contains functional tests for FEs using crafted and/or generated media files
to verify that the FEs are working as expected:

 - laughter detection -- uses videos with laughs at known times
 - video activity -- uses videos with visual activity at known times
 - audio loudness -- uses videos with audio at known times

etc.

These tests are marked slow to avoid running them during normal test runs.
