From 63207bbc8c5f791d1ca5565db39a8e2400165e7b Mon Sep 17 00:00:00 2001 From: Elliott Sales de Andrade Date: Fri, 13 Feb 2026 23:21:46 +0530 Subject: [PATCH] TST: Use correct method of clearing mock objects In Python 3.13.12 and 3.14.3, fixes for thread-safety of mock `call_count` meant that manually changing it no longer works [1]. Instead use the more correct `reset_mock` method.
