After d236893, only some unit tests for the Template class class methods remain:

ancv/ancv/visualization/templates.py

Lines 89 to 128 in d236893

	@classmethod
	# A property would be nicer but it's not supported from Python 3.11 on:
	# https://docs.python.org/3.11/library/functions.html#classmethod

	return {cls.__name__: cls for cls in cls.__subclasses__()}
	@classmethod

	try:
	theme = THEMES[model.meta.config.theme]
	except KeyError as e:

Closed by now. The above is covered by integration tests for the CLI, and all sorts of units tests are implemented by now.
