The comment references "covers line 114" but this appears to be inaccurate or outdated. Based on the handler.py code, line 114 contains the check for rollback_content being None. Consider updating this comment to reflect the actual purpose of the test without referencing specific line numbers, which can become outdated as code evolves. For example: "Test parsing fails when rollback_content variable is None".

Suggested change

	"""Test parsing fails when rollback_content variable is None (covers line 114)"""
	"""Test parsing fails when rollback_content variable is None"""

The import mock_open is unused in this test file. Consider removing it to keep the imports clean and maintain code quality.

Suggested change

	from unittest.mock import MagicMock, patch, mock_open
	from unittest.mock import MagicMock, patch

Import of 'RollbackContext' is not used.

Suggested change

from krkn.rollback.config import RollbackContext

The usage documentation suggests running tests with pytest, but the test file uses unittest.TestCase throughout and has a if __name__ == "__main__": unittest.main() block. For consistency, consider updating the usage example to use unittest instead. For example: python3 -m coverage run --source=krkn -m unittest tests/rollback/test_handler.py -v

Suggested change

	python3 -m coverage run --source=krkn -m pytest tests/rollback/test_handler.py -v
	python3 -m coverage run --source=krkn -m unittest tests/rollback/test_handler.py -v
