Measured before choosing: 86.17%, identical via `mix test --cover` and via the
exported sample + `mix test.coverage`, stable across seeds. Floor is the integer
below that, with the rule written next to it: a FLOOR, ratcheted up as
behavior-test yaks land, never lowered (a drop means the change or an exclusion
is wrong).
Exclusions are the modules the suite cannot or should not exercise, each
justified in the config comment: `use`-generated glue (Repo, Mailer, Telemetry,
ErrorHTML/ErrorJSON), the `use FirehoseWeb` macro, production release tasks
(Release), the lib_dev credo check (NoConnShadowing), and test scaffolding
(DataCase, ConnCase, AccountsFixtures, Test.FakeBlog). Everything else counts,
CoreComponents/controllers/LiveViews included.
Wiring matches blogex and the fast/push split: `test.coverage` runs the suite
once with `--cover --export-coverage default` (deleting stale exports first,
since `mix test.coverage` imports every .coverdata it finds and would pool
them), then the `coverage` sensor enforces the floor from that export. The
sensor guards on the export existing because `mix test.coverage` exits 0 when it
finds nothing — a floor check that did not run must not pass.
Root verify runs check first, then a per-app verify in each Makefile: sensor
slots hooked to VERIFY_SENSORS (empty today, so nothing is claimed that is not
run) and then that app's suite. Measured: 9.9s wall, app 178 + blogex 156 tests.
mise now lives at /opt/homebrew/bin/mise (Homebrew install), so the
hardcoded MISE_BIN default broke make test/deps/compile. Fall back to
PATH lookup, matching what the check target already did.
1. Rename goto_engineering_post_page/2 to visit_engineering_path/2 for
better accuracy (used for both post pages and tag pages)
2. Simplify Makefile test target by removing explicit ecto.create and
ecto.migrate commands (mix test handles migrations automatically)
3. Update blog_test.exs header comment to reflect actual changes made
4. Move Sandbox alias to top level in data_case.ex
