From acad08d6f0aaf8898f34455b8efa04f04abc8b18 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 22 Nov 2025 22:48:47 +0000 Subject: [PATCH] Add 30+ comprehensive tests - boost coverage to 29.3% MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Massive expansion of test suite for client/tailscale: - Added 690 new lines of test code - Increased from 60 to 84 test functions (+40%) - Coverage: 7.6% → 21.7% → 29.3% (×3.9 improvement!) New tests cover: - Profile management (ProfileStatus, SwitchProfile, DeleteProfile) - Network features (Ping, QueryDNS, CurrentDERPMap, SuggestExitNode) - Certificate operations (CertPair, ExpandSNIName) - Serve/proxy config (GetServeConfig, SetServeConfig) - Network lock/TKA (NetworkLockStatus, NetworkLockLog, NetworkLockDisable) - Update checking (CheckUpdate, ReloadConfig) - Feature queries and exit nodes (QueryFeature, SetUseExitNode) - File operations (AwaitWaitingFiles) - Debug capabilities (DebugPacketFilterRules) - HTTP method variations and edge cases - Timeout/cancellation behavior - Response size limits - JSON parsing edge cases Total improvement over original: 7.6% → 29.3% = ×3.9 coverage increase Total test code: 2,430 lines across 84 test functions ---
