Zero-dependency coverage gate: read your existing LCOV or json-summary report, show the gap to a target (default 80%) and the lowest-covered files, and fail CI when below target.
A zero-dependency coverage gate for JavaScript and TypeScript projects. It reads
the coverage report your test run already produced (LCOV or Istanbul
json-summary), prints your current line coverage, the gap to a target (default
80%), and your lowest-covered files, and fails CI when you are below target.
No network calls, no account, no dependencies. It works with jest, vitest, nyc,
and c8, anything that can emit lcov.info or coverage-summary.json.
# after running your tests with coverage
npx taskbounty-coverage-gate --min 80
It auto-detects coverage/lcov.info, coverage/coverage-summary.json,
coverage-summary.json, or lcov.info. Point it explicitly with --report:
npx taskbounty-coverage-gate --report coverage/lcov.info --min 80
Options:
| Flag | Default | Meaning |
|---|---|---|
--report <path> | auto | Path to the LCOV or json-summary report |
--min <pct> | 80 | Target line coverage |
--top <n> | 5 | How many lowest-covered files to list |
--no-fail | off | Report only, always exit 0 |
Example output:
Coverage gate (report: coverage/lcov.info)
Line coverage 62.4% ███████████████░░░░░░░░░
Target 80.0%
Result BELOW target by 17.6 points
Lowest-covered files:
0% src/api/webhooks.ts
31% src/billing/invoices.ts
44% src/auth/session.ts
Exit code is 1 when below target (so it gates CI), 0 otherwise or with
--no-fail.
