This PR adds comprehensive unit tests for the remaining app-level workers to address issue #489.

Changes

  • AppWorker tests (22 passing tests): Covers constructor, run lifecycle, environment variable handling, message forwarding, error handling, and shutdown
  • App cluster tests (25+ tests): Covers cluster initialization, worker forking, message broadcasting, worker restart on exit, and configuration validation
  • StaticMirroringWorker tests (30+ tests): Covers event filtering, balance checking, whitelist/blacklist validation, and admission controls

Test Coverage

  • Worker lifecycle (start, stop, error handling) ✅
  • Dependencies stubbed (repositories, adapters, services) ✅
  • Configuration handling ✅
  • Signal handling (SIGTERM, SIGINT, SIGHUP) ✅
  • Environment variable handling ✅
  • Error recovery and logging ✅

Status

  • AppWorker: Complete (all tests passing)
  • App: Complete (most tests passing, minor timing issue with restart scheduling)
  • StaticMirroringWorker: Core functionality covered (some tests need config initialization refinement)

Note

The test suite requires the ESM loader to run properly due to TypeScript parameter properties:

NODE_OPTIONS="--loader ts-node/esm --experimental-specifier-resolution=node" npm run test:unit

Add dorny/paths-filter gate so lint, build-check, and both test jobs
only run when source-affecting files change (src/, test/, package.json,
tsconfigs, Dockerfiles, etc.). Metadata checks (commit-lint,
changeset-check) remain unconditional.

Also restrict commit-lint to PRs/workflow_dispatch to avoid false
positives on squash-merge commits pushed to main, fix post-tests
Coveralls parallel-finished to not fire on skipped test runs, and bump
actions/checkout + actions/setup-node from v3 to v4.
Resolves conflicts by:
- Keeping path filter optimization (changes job + conditional skipping)
- Adopting pnpm package manager from main
- Upgrading GitHub Actions to v4 for security/performance
- Updating lock file path from package-lock.json to pnpm-lock.yaml
- Changing npm commands to pnpm equivalents
- Removing redundant npm-based changeset entry
- Adds comprehensive unit tests for AppWorker (22 test cases, all passing)
- Adds unit tests for StaticMirroringWorker (30+ test cases)
- Adds unit tests for App cluster coordinator (25+ test cases)
- Tests cover lifecycle (start, stop, error handling)
- Tests cover configuration and environment variables
- Tests cover cluster message broadcasting and worker management
- Dependency stubs (repositories, adapters, services)

Increases test coverage for src/app/worker.ts and src/app/app.ts.
Partial coverage for src/app/static-mirroring-worker.ts.
Further refinement of StaticMirroringWorker tests needed to properly
initialize worker.config before testing isUserAdmitted method.

Acceptance criteria for issue #489:
- Worker lifecycle tests: ✅
- Error handling: ✅
- Dependencies stubbed: ✅
- npm run cover:unit passes: Partial (need ESM loader configuration)
