Gives linux_configuration/scripts/lib a real test suite, which takes all nine of its libraries off meta/shell-coverage-allowlist.txt at once — coverage is per-directory, so this is the highest-ratio first batch. 139 assertions across four suites, all offline: the mtk toolkit is driven through its existing MTK_ROOT_FIXTURE seam, and adb is shimmed onto a narrowed PATH. Nothing reads the wall clock, this host's udev rules, or a real device, because the suite runs in shell-tests.yml and again on every pre-push via ci-mirror — a host-dependent assertion would be a flake that blocks unrelated pushes. The gate only checks that tests/run_all.sh EXISTS, so an empty one would mark all nine libraries covered while testing nothing. Each of the four load-bearing rules was therefore mutation-tested and the suite required to go red: classify_device's && -> ||, discover_partitions' init_boot/boot ordering, mtk_select_device's refusal to guess between two phones, and is_hour_in_range's 10#$ octal guard. That last one initially SURVIVED. Dropping 10#$ makes bash abort with "value too great for base", a non-zero exit indistinguishable from an honest out-of-range result, so the status-only assertion passed either way. It now asserts stderr is empty. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |
