4gray 08b868d6c1 test(electron): harden runtime boundary coverage (#1267)
Adds contract-focused regression coverage for the Electron HTTP server,
remote-control events, settings events, and managed download paths, and makes
Tier A coverage fail closed when instrumentation fails or a runtime-owning
production file disappears from a project or from the merged Istanbul report.

The old `coverage:ci` exited 0 despite a `Failed to collect coverage`
diagnostic: libs/m3u-state/src/lib/effects.ts was simply absent from the merged
map. All 30 Tier A reports are now required, the merged map covers 710 files,
and effects.ts is reported as 0/159 instead of silently disappearing.

Also fixes remote static-file path containment for encoded, malformed, NUL,
POSIX and Win32-style traversal inputs, with behavior-preserving testability
seams.

Statements 69.27% -> 69.54%; http-server.ts 0% -> 90.21%,
remote-control.events.ts 0% -> 96.55%, settings.events.ts 59.25% -> 96.29%.

Validation Map

This map records the lowest-cost validation commands agents should reach for before broad CI-sized runs.

Discovery

pnpm nx show projects --withTarget test
pnpm nx show projects --withTarget lint
pnpm nx show projects --withTarget e2e

Unit And Type Checks

Area Command
Angular renderer entry points pnpm run typecheck:web
Electron main process entry points pnpm run typecheck:backend
Full unit suite (all projects) pnpm run test:unit:ci
EPG data access pnpm nx test epg-data-access
Workspace shell utilities pnpm nx test workspace-shell-util
Shared SQLite schema/connection pnpm nx test database
Packaging metadata pnpm nx test packaging

Lint

pnpm run lint                 # nx run-many --target=lint --all
pnpm nx lint <project>        # single project

The CI workflow (.github/workflows/ci.yml) lints affected projects on PRs (nx affected) and every project on master pushes. This enforces @nx/enforce-module-boundaries (scope/domain/type tag constraints), the legacy bare-alias ban, and the max-lines file-size rule (hard maximum 400 lines per TypeScript file). Files that predate the max-lines rule are baselined in tools/eslint/max-lines-baseline.mjs; after splitting a baselined file below the limit, regenerate the list with node tools/eslint/generate-max-lines-baseline.mjs. Never add new files to the baseline.

Coverage Tiers

Use tools/coverage/coverage-policy.json as the source of truth for coverage ownership. Every project with a test target must be classified in a tier; pnpm run coverage:policy:check (part of coverage:ci) fails CI when a new project is missing from the policy, a listed project no longer exists, or a Tier A entry has no test target. CI runs Tier A with coverage (uploaded to Codecov) and each Tier B/C project's validationCommand (falling back to nx test) without coverage; projects with an e2e target are skipped there because the E2E workflow already runs them on every PR that touches app code. Docs-only changes (Markdown, docs/, .plans/, .codex/, .claude/) and apps/website/** changes skip the E2E workflow via paths-ignore — for those PRs no E2E validation runs in CI, which is intentional: they cannot affect app behavior.

Tier A coverage is fail-closed. coverage:unit:ci relays Jest output but exits nonzero on a Failed to collect coverage marker, a missing or invalid project report, or a runtime-owning production TypeScript file absent from that report. coverage:merge requires every configured Tier A report before replacing the merged output. Strict health validation also requires the merged Istanbul map itself to contain usable instrumentation for every runtime-owning Tier A file, recomputes its summary, and then applies aggregate and selected critical-file ratchets.

Runtime-owning files are discovered from the TypeScript AST. Specs, declarations, test setup and stubs, generated and environment files, index.ts, type-only files, and pure re-export shims are excluded. Ratchets live under reporting.coverageRatchet in tools/coverage/coverage-policy.json; update them only from a fresh full coverage:ci report when every value stays level or rises, and never lower one to accept a regression. The only exception is an explicitly reviewed production source shrink: minimumCovered may follow a lower total statement count when the PR documents the removed executable statements and fresh coverage proves that the corresponding minimumPercent, every aggregate ratchet, and the remaining behavioral coverage do not decrease.

Tier Rule Validation
A Product/runtime Angular, Electron, backend, data-access, portal, playlist, workspace, playback, EPG, and shared UI code collects source coverage. pnpm run coverage:ci
B Validate behavior without percentage coverage, such as website, packaging, and Playwright E2E projects. pnpm nx test website, pnpm nx test packaging, or the closest E2E target
C Excluded from the source coverage baseline, such as mock servers, test helper libraries, and untested feature shells. Validate through dependent flows, or add focused tests when changing behavior directly

apps/website is an Astro marketing site. Its useful signal is a successful static build plus targeted output checks, not a merged code coverage percentage. Projects with a test target but no specs, such as remote-control-web and remote-control today, should not be in Tier A until focused specs exist.

For local coverage inspection:

pnpm run coverage:tools:test
pnpm run coverage:unit:ci
pnpm run coverage:merge
pnpm run coverage:health -- --require-report

The merged report is written to coverage/merged/ as HTML, LCOV, Cobertura, and JSON summary output. CI uploads the merged Tier A report to Codecov with the unit flag and keeps the HTML report as a GitHub artifact.

E2E

Area Command
Web app browser flows pnpm nx run web-e2e:e2e -- --project=chromium
Electron flows pnpm nx run electron-backend-e2e:e2e

Use atomized E2E targets when available, for example pnpm nx run web-e2e:e2e-ci--src/xtream.e2e.ts.

Playwright coverage is measured semantically by tags and critical journeys, not by a source-line percentage. E2E reports should use tags such as @critical, @electron, @web, @xtream, @stalker, @m3u, @search, @epg, @persistence, @settings, @pwa, and @self-hosted.

After an E2E run, generate the semantic summary with:

pnpm run coverage:e2e:summary

For local investigation only, Chromium browser V8 coverage can be explored with:

pnpm run coverage:e2e:v8:web

I18n

pnpm run i18n:check

The i18n check is non-mutating. It compares every locale file in apps/web/src/assets/i18n/ against en.json and fails on missing or extra keys. Identical English fallback values are reported as warnings by default; use node tools/i18n/check-drift.mjs --fail-on-identical for a stricter translation audit.

Logging

Runtime playback and EPG debug logs should use the existing logger or trace helpers instead of unconditional console.log. Electron external-player traces are gated by:

IPTVNATOR_TRACE_PLAYER=1 pnpm run serve:backend
