From 1e49178c3ebd1469dad6685db16698b3dae7cf8c Mon Sep 17 00:00:00 2001 From: torlando-tech Date: Sun, 18 Jan 2026 15:04:08 -0500 Subject: [PATCH] test: use real BLEInterface instances for coverage tracking Replace Mock-based fixtures with real BLEInterface instances in stale identity check tests. This ensures coverage.py properly tracks execution of production code paths. The Mock approach with method binding executed the production code but coverage tracking was inconsistent. Using real instances guarantees proper coverage attribution.
