ci: fail the run when suspiciously few tests were counted - #275
Conversation
A green `vitest run` only proves that everything that ran passed — it says nothing about whether everything that should have run, ran. A test file that never registers its tests (a rename that slips out of the include globs, a directory dropped from the config, an import-time throw swallowed as an empty collection) leaves the surviving files passing and CI green with a chunk of the suite silently missing. scripts/test-floor.mjs closes that gap: it runs the same suite with a JSON reporter alongside the console one, counts the tests the run registered, and fails below TEST_COUNT_FLOOR (970 — roughly 90% of today's 1081 tests, a floor rather than an exact count so ordinary churn never touches it). It also refuses to report a pass when the count cannot be determined at all, because an uncountable run has exactly the shape of a collection failure. Registered tests are counted rather than executed ones so the POSIX-only tests that self-skip on Windows do not force a per-platform floor. The `test` script's leading `vitest run` becomes `node scripts/test-floor.mjs`; ci.yml is untouched and the broker/updater/packaged-server legs run as before. The pass/fail decision is a pure function with its own unit tests, which run inside the counted suite via a new scripts/**/*.test.mjs include glob.

What
CI now fails when suspiciously few tests were counted, even if every one of them passed.
pnpm test's leadingvitest runis replaced bynode scripts/test-floor.mjs, which runs the exact same suite with a machine-readable JSON reporter alongside the normal console reporter, counts the tests the run registered, and fails below a floor of 970 (roughly 90% of the 1081 tests in the suite today). It also refuses to report a pass when the count cannot be determined at all — a run that cannot be counted has exactly the shape of a collection failure.Why
A green test run only proves "everything that ran passed". It says nothing about whether everything that should have run, ran. A test file that never registers its tests — a rename that slips out of the include globs, a directory dropped from the vitest config, an import-time throw swallowed as an empty collection — leaves the remaining files passing and CI green with a chunk of the suite silently missing. The floor adds the other half of the claim: "and roughly everything we expected to run, ran."
Design choices, all commented in
scripts/test-floor.mjs:TEST_COUNT_FLOORbecomes a visible, reviewed decision in that same PR.testscript chain — least invasive option: ci.yml is untouched, CI still runspnpm test, and the other legs (broker:test,test:updater,test:packaged-server) run exactly as before. Localpnpm testgets the same protection for free;test:watchstays plain vitest.evaluateRun) so it can be unit-tested without spawning a nested suite;scripts/test-floor.test.mjspins down every branch (below floor, uncountable summary, nonzero exit, signal death,success: falsewith exit 0). Those tests run inside the counted suite via a newscripts/**/*.test.mjsinclude glob.Test plan
pnpm typecheck— clean.pnpm test(floor gate + broker + updater + packaged-server) — green; the floor leg counts 1087 tests against the 970 floor.scripts/test-floor.test.mjs, all passing.node scripts/test-floor.mjsexits 1 withonly 1087 tests were counted, below the floor of 99999— the gate demonstrably fires end-to-end, not just in unit tests.🤖 Generated with Claude Code
