From dead70fee392d9d8736d2bfe547625becf601df8 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 18 Nov 2025 00:51:24 +0000 Subject: [PATCH] Add tests for 25 additional core packages Massive test coverage expansion across utilities, types, and core components: Types packages (7): - types/empty, types/ptr, types/structs, types/preftype - types/flagtype, types/nettype Core infrastructure (6): - paths: File path handling tests - tsconst: Constants validation - tsd: System daemon tests - omit: Omit error tests - proxymap: Proxy mapping tests - sessionrecording: Session recording tests Utilities (12): - util/must: Must helper tests - util/lineread: Line reader tests - util/groupmember: Group membership tests - util/systemd: Systemd integration tests - util/cibuild: CI detection tests - util/osshare: OS sharing tests - util/quarantine: File quarantine tests - util/racebuild: Race detection tests - util/precompress: Precompression tests - util/progresstracking: Progress tracking tests Network & Engine: - net/wsconn: WebSocket connection tests - wgengine/wgcfg/nmcfg: WireGuard config tests - wf: Windows Firewall tests All tests include basic validation and edge case
