Testing

Stack

Layer	Tool
Test runner	Vitest v4
HTTP integration	supertest
HTTP interception	nock (intercepts at Node http layer — works with CJS require('axios'))
Coverage	V8 (built-in, no Babel needed)

Running tests

# Run all tests once
npm test

# Watch mode (re-runs on file change)
npm run test:watch

# With coverage report
npm run test:coverage

# Interactive UI
npm run test:ui

Coverage output lands in coverage/ (gitignored). Open coverage/index.html for the HTML report.

Key design decisions

• server/app.js — Express factory extracted from server/index.js. Tests import createApp() without triggering the log-file setup, process.exit() calls, or background poller in the entry point.
• nock over vi.mock('axios') — Vitest's vi.mock only intercepts ESM import statements. Since auth.js uses CJS require('axios'), nock (which patches Node's http/https modules) is the correct tool for intercepting outbound requests.
• SKIP_RATE_LIMIT=1 — All supertest requests originate from 127.0.0.1, which would quickly exhaust per-IP rate-limit windows. Setting this env var raises the limits to Number.MAX_SAFE_INTEGER in both the API limiter and the login limiter.
• Isolated DATA_DIR — Each test worker gets a unique temp directory so tokenStore.js file I/O never conflicts with a running dev server.
• createApp({ skipRateLimits: true }) — The app factory accepts an option to disable the general API rate limiter in addition to the env var for the login-specific limiter.

Coverage targets

Global thresholds (enforced in CI via vitest.config.js):

Metric	Threshold
Statements	55%
Functions	55%
Branches	40%
Lines	55%

Notable per-file coverage after the current suite:

File	Lines	Branches	Notes
server/app.js	~92%	~71%
server/routes/auth.js	~88%	~78%
server/routes/dashboard.js	~42%	~25%	SSE /stream endpoint intentionally untested
server/routes/emby.js	100%	100%
server/routes/radarr.js	~87%	~77%
server/routes/sonarr.js	~89%	~82%
server/routes/sabnzbd.js	100%	100%
server/routes/webhook.js	~85%	~79%
server/middleware/requireAuth.js	~92%	~81%
server/middleware/verifyCsrf.js	100%	80%
server/utils/sanitizeError.js	100%	75%
server/utils/config.js	~70%	~58%

poller.js (background polling engine) and the SSE /stream endpoint in dashboard.js require time-based behaviour and long-lived HTTP connections; they remain tracked as future test coverage work.
