* test: cover pure-logic gaps found by the coverage auditCraig Jennings7 days1-0/+25
| | | | | | | | I ran make coverage and worked the report function by function, separating real gaps from interactive/IO wrappers that aren't unit-test targets. These tests fill the genuine pure-logic holes: predicates, parsers, formatters, transforms, and three modules that had no test file at all. New files cover car-member (local-repository), show-kill-insert-item (show-kill-ring), the oauth2-auto plstore cache fix (auth-config), the coverage-core project-root fallback, reconcile--dirty-p, and the recurrence-frequency dispatch in calendar-sync. Extended files add the missing branches: coverage-core's merge-base and diff /dev/null handling plus the staged and branch-vs-main scopes, the detect-system-timezone symlink path, user-constants no-op and optional-failure branches, the elfeed playlist branch with HTML-entity decoding, the duplicate-line no-comment-syntax guard, and several calendar-sync edges (exception field overrides, timestamp seconds and TZID fallback, property-line position advancement, parse-ics nil and out-of-range inputs). Mocks sit at the real boundaries (plstore, url-retrieve, process-file, git) so each function's own logic runs. Dates come from relative helpers. About 65 tests added across 15 files, and the full suite stays green.
* test(host-environment): cover laptop/desktop, platform, display, timezone ↵Craig Jennings2026-04-301-0/+78
predicates Four new test files extending the existing test-host-environment.el (which already covered the two battery helpers). - platform-predicates: env-linux-p, env-bsd-p, env-macos-p, env-windows-p walked across every supported system-type value. 8 tests. - display-predicates: env-x-p, env-x11-p, env-wayland-p, env-terminal-p, env-gui-p exercised under every relevant combination of window-system, WAYLAND_DISPLAY, and display-graphic-p. 13 tests. - env-laptop-p: composition over the helpers, with Linux dispatch isolated from non-Linux dispatch via system-type binding. 8 tests including env-desktop-p as the inverse. battery-status-function is forward-declared in this test file (initialized to nil) so cl-letf's symbol-value place can read the prior value without hitting void-variable. - detect-system-timezone: the four-method priority chain. Mocks cj/match-localtime-to-zoneinfo and getenv at the boundary; uses cl-letf on file-exists-p / insert-file-contents to exercise the /etc/timezone fall-through without touching real system files. 5 tests. 34 new tests for host-environment, all passing. Full suite green.
