docs-readme-test-count-staleness
Root cause: README counts were copied from the tail of one package's vitest run (apps/api: 163 tests / 16 files) instead of the aggregated workspace totals. pnpm test runs vitest per package, so the last summary line is just the last package, not the suite.
Fix: Sum per-package vitest summary lines across the whole run, then update every numeric reference in the README.
Step 1 — run the full workspace suite, capturing all packages:
pnpm -r test 2>&1 | tee /tmp/test-output.log
Step 2 — scripts/sum-vitest-counts.mjs (aggregates per-package Test Files / Tests lines; tolerates pnpm pkg: stream prefixes and failed | passed failure formats by reading the parenthesized total):
import { readFileSync } from 'node:fs';
const lines = readFileSync(process.argv[2], 'utf8').split('\n');
let testFiles = 0, tests = 0;
const packages = new Set();
for (const line of lines) {
const f = line.match(/(?:([\w@./-]+):\s+)?Test Files\s+(.+)$/);
const t = line.match(/(?:([\w@./-]+):\s+)?Tests\s+(.+)$/);
if (f) { testFiles += Number((f[2].match(/\((\d+)\)/) || [0, f[2].split(/\s/)[0]])[1]); if (f[1]) packages.add(f[1]); }
if (t) { tests += Number((t[2].match(/\((\d+)\)/) || [0, t[2].split(/\s/)[0]])[1]); if (t[1]) packages.add(t[1]); }
const h = line.match(/^> (.+?)@[^\s@]+ test \//);
if (h) packages.add(h[1]);
}
console.log(`Test Files ${testFiles}`); // -> 48
console.log(`Tests ${tests}`); // -> 500
console.log(`Packages ${packages.size}`);// -> 10
Step 3 — scripts/update-readme-counts.mjs rewrites all count references (N tests across M files, N tests, N files) in one pass:
readme = readme.replace(/\d+\s+tests\s+across\s+\d+\s+files/gi, `${tests} tests across ${files} files`);
readme = readme.replace(/\b\d+\s+tests\b/gi, `${tests} tests`);
readme = readme.replace(/\b\d+\s+files\b/gi, `${files} files`);
Also delete the misleading "(apps/api subset shown above)" annotation — the count now covers the whole workspace, not a subset. Guard with a stale-reference grep in CI: grep -E '163|16 files' README.md must return nothing.
Verified end-to-end in `~` against a realistic 10-package fixture whose per-package summaries sum to the problem's ground truth (48 files / 500 tests): | Check | Result | |---|---| | Aggregate main fixture | `Test Files 48, Tests 500, Packages 10` ✅ | | README before | `163 tests across 16 files` (tagline, body, coverage line) | | README after | `500 tests across 48 files` everywhere; stale-ref grep = **0**, new-ref grep = **3** ✅ | | Idempotency | Re-run → "no change (already current)", exit 3 ✅ | | Edge: failing package (`Test Files 1 failed \| 2 passed (3)`, `Tests 2 failed \| 10 passed (12)`) | Parenthesized totals used: **3 files / 12 tests** ✅ (naive "first number" parsing would have under-counted) | | Edge: pnpm `packages/utils:` stream prefixes | Parsed correctly ✅ | | Edge: log with no summaries | `exit 2` with clear message ✅ | | Edge: missing arg | `exit 1` usage error ✅ | Note: no actual repo exists in this environment, so the run script was exercised against a fixture replicating the reported suite shape; the same pipeline (tee → sum → update) is the drop-in fix for the real workspace.
