Standalone tests for the MaintenanceTaskRunner.
|
|
|
|
These tests work without OpenHands dependencies and focus on testing the core
|
|
logic and behavior of the task runner using comprehensive mocking.
|
|
|
|
To run these tests in an environment with OpenHands dependencies:
|
|
1. Ensure OpenHands is available in the Python path
|
|
2. Run: python -m pytest tests/unit/test_maintenance_task_runner_standalone.py -v
