Pull Request Overview
This PR creates comprehensive planning documentation for F003 test coverage improvements, establishing a roadmap to increase test coverage from 78.75% to 90%+ through systematic testing of untested components (main server entry point and resource handlers), integration tests for E2E workflows, and edge case testing.
Key Changes:
- Tasks breakdown: 106 tasks organized across 7 phases (setup, foundational, 4 user stories, polish) with clear dependencies and parallel execution opportunities
- Research documentation: Resolves 6 technical unknowns including MCP server mocking strategy, test data management, performance targets, CI/CD integration, coverage thresholds, and concurrent access testing
- Implementation guides: Comprehensive quickstart guide (923 lines), implementation plan (780 lines), and developer-focused documentation to facilitate execution

The year "2025-11-17" is used throughout these documents as the "Last Updated" date, but based on the context (January 2025 knowledge cutoff, currently November 2025), this appears to be a typo. The date should likely be "2024-11-17" or the current actual date in November 2025.

Inconsistent date format - this document uses "2025-11-17" while it should likely be "2024-11-17" to match the actual timeline (given the context that the knowledge cutoff is January 2025 and it's currently November 2025).

Inconsistent date format throughout the document. The "Created" date shows "2025-11-17" which is inconsistent with expected timeline (should be 2024-11-17).

TESTING.md Comprehensive Guide (docs/guides/) - Test organization and structure - Testing patterns (Tool, State, Integration, Resource) - Coverage requirements and current metrics - Best practices and anti-patterns - Common patterns and helpers - CI integration details - Troubleshooting guide 3. Test Fixture Documentation (src/__tests__/fixtures/) - Purpose and usage of each fixture - valid-state.json - Standard state structure - complete-state.json - All gears completed - corrupted-state.json - Error handling - proto-pollution.json - Security testing - Best practices for fixtures - Dynamic vs static test data Test Quality Verification: - ✅ Ran tests 3+ times - no flaky tests detected - ✅ Test execution time: ~4.7s (target: <60s) - ✅ All 338 tests passing consistently - ✅ Coverage stable at 84.97% CI Integration: - Existing .github/workflows/ci.yml already configured - Coverage runs on Node 20.x - Automatic Codecov upload - Threshold enforcement via vitest.config.ts Coverage Breakdown: - Overall: 84.97% (lines/statements), 90.25% branches, 93.33% functions - Tools: 98.49% coverage - Resources: 94.21% coverage - Utils: 95.55% coverage - index.ts: 0% (expected - heavy MCP SDK mocking) Addresses: F003-test-coverage US4 (CI/CD), Phase 7 (Polish) Related: production-readiness-specs/F003-test-coverage/tasks.md (T090-T106)
