+## Test Helpers — No Duplicate Mocks
+
+Reuse shared mocks and factories from `test/db_test_helpers.py`. Never redefine `DummyDB`, `make_db`, or inline DDL in individual test files.
+
+```python
+import sys, os
+sys.path.insert(0, os.path.join(os.path.dirname(__file__), ".."))
+from db_test_helpers import make_db, DummyDB, insert_device, minutes_ago
+```
+
+If a helper you need doesn't exist yet, add it to `db_test_helpers.py` — not locally in the test file.
+
 ## Path Hygiene
 
 - Use environment variables for runtime paths

 * **Increase scan intervals** (`<PLUGIN>_RUN_SCHD`) on busy networks or low-end hardware.
 * **Increase timeouts** (`<PLUGIN>_RUN_TIMEOUT`) to avoid plugin failures.
 * **Reduce subnet size** – e.g., use `/24` instead of `/16` to reduce scan load.
+* **Enable the deep sleep setting** (`DEEP_SLEEP`) – Lowers CPU usage by extending idle wait times between processing cycles. When enabled, scans may be delayed by up to 1 minute and the UI might become less responsive.
 
 Some plugins also include options to limit which devices are scanned. If certain plugins consistently run long, consider narrowing their scope.
