From 2c537f0680ec36320dfa2279ef710fa4920e3580 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 20 Jun 2026 14:04:21 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=A7=AA=20[testing=20improvement]=20Add=20?= =?UTF-8?q?AStar=20tests?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Implemented comprehensive unit tests for AStar pathfinding algorithm - Tested directed, undirected, disconnected, missing nodes, null heuristics, and grid paths - Fixed StackOverflowException caused by infinite recursion for undirected edges by ensuring mirrored edges specify IsDirected = true. - Brought AStar line coverage up to 97.8% Co-authored-by: johnstrand
