# land; never lower it. A drop means the change (or an exclusion) is wrong,
|
|
# not the floor.
|
|
#
|
|
# Measured 2026-10-29 (PostgreSQL on localhost:5432, exclusions below):
|
|
# 94.01% on `main` = 9c0f33e, with boundary enforcement, credo, the mutation
|
|
# scope and the core-components behavior tests all landed (88.19% after the
|
|
# web-controller/auth edge-case tests, 87.56% after the editorial-LiveView
|
|
# ones, 86.97% before them, and 86.79% / 86.17% at earlier exclusion
|
|
# revisions), identical via `mix test --cover` and via
|
|
# `mix test --cover --export-coverage default` + `mix test.coverage`. Floor is
|
|
# the integer below that — so a floor of 94 means "at least 94.00%".
|
|
#
|
|
# `test.coverage` deletes stale exports before sampling: `mix test.coverage`
|
|
# imports *every* .coverdata it finds, so leftover exports from earlier runs
|
|
# pool into the total and quietly inflate it.
|
|
#
|
|
# Excluded are modules the suite cannot or should not exercise; counting them
|
|
# would move the number without saying anything about app behavior:
|
|
#
|
|
# * framework glue generated by `use`:
|
|
# Firehose.Repo `use Ecto.Repo`
|
|
# Firehose.Mailer `use Swoosh.Mailer`
|
|
# FirehoseWeb.Telemetry Phoenix's telemetry supervisor + metric list
|
|
# FirehoseWeb.ErrorHTML Phoenix error renderers, both delegating to
|
|
# FirehoseWeb.ErrorJSON Phoenix.Controller.status_message_from_template/1
|
|
# * FirehoseWeb the `use FirehoseWeb` macro: imports and aliases
|
|
# only, nothing that executes
|
|
# * embed_templates wrappers FirehoseWeb.BlogHTML,
|
|
# FirehoseWeb.UserRegistrationHTML,
|
|
# FirehoseWeb.UserSettingsHTML: each is `use` +
|
|
# `embed_templates`, so every function in them is
|
|
# generated by the macro. Their TEMPLATES are
|
|
# exercised through the controller tests; the
|
|
# wrapper modules hold no hand-written code.
|
|
# NOTE: PageHTML and UserSessionHTML are
|
|
# deliberately NOT excluded — both carry private
|
|
# helpers with real logic (blog_label,
|
|
# post_base_path, local_mail_adapter?), so their
|
|
# gaps are behavior gaps, not macro noise.
|
|
# * Firehose.Application start/2 is proven by the suite booting at all (a
|
|
# broken supervision tree fails every test), and
|
|
# config_change/3 only runs on a release hot
|
|
# upgrade, which no test can reach.
|
|
# * Firehose.Release production release tasks (`mix ecto.migrate` on
|
|
# Dokku); the suite never runs them
|
|
# * test scaffolding Firehose.DataCase, FirehoseWeb.ConnCase,
|
|
# Firehose.AccountsFixtures, Firehose.Test.FakeBlog:
|
|
# fixtures measure the tests, not the app
|
|
#
|
|
# `Firehose.Checks.NoConnShadowing` needs no entry: lib_dev/ is no longer in
|
|
# elixirc_paths (credo loads it from source), so it is not measurable here.
|
|
#
|
|
# Everything else counts — CoreComponents, controllers, LiveViews included:
|
|
# that is where the behavior-test work shows up as a higher floor.
