📊 Test Coverage Report — 2026-08-10

Overall Coverage

Metric	Coverage	Details
Lines	94.16%	8,937 / 9,491 covered
Statements	93.08%	9,320 / 10,012 covered
Functions	93.91%	1,266 / 1,348 covered
Branches	86.28%	5,038 / 5,839 covered

Status: ✅ Excellent overall coverage with strong statement and function coverage. Branch coverage is lower, indicating some conditional logic paths need test scenarios.

---

🛡️ Security-Critical Path Status

All security-critical components have strong coverage:

Module	Statements	Branches	Functions	Status
src/host-iptables.ts	100%	0% (0 branches)	100%	✅ SECURE
src/squid-config.ts	100%	0% (0 branches)	100%	✅ SECURE
src/docker-manager.ts	100%	0% (0 branches)	100%	✅ SECURE
src/domain-patterns.ts	100%	89.47%	100%	✅ SECURE
src/cli.ts	85.71%	50%	100%	⚠️ PARTIAL

Key Finding: Network isolation and domain filtering logic has complete statement coverage. The main entry point (cli.ts) has a missing branch; this is low-risk as it's a thin orchestration layer.

🔧 Function Audit

High-Value Functions (Well-Tested)

• ✅ generateSquidConfig() — Fully tested domain ACL generation
• ✅ setupDockerNetwork() — Container network orchestration
• ✅ validateDomainPatterns() — Domain whitelist validation
• ✅ aggregateLogs() — Log parsing and analysis

Partially-Tested Functions

• ⚠️ cli.ts entrypoint — Missing 1 branch scenario (exit path error handling)
• ⚠️ enclave/runtime-preflight.ts — 70% coverage, missing error paths
• ⚠️ firecracker/api-client.ts — 84.41% coverage, some retry logic untested

📅 Recent Source Changes (last 7 days)

Recent additions and modifications to test coverage:

• src/bounded-execution/finite-disclosure.ts (CRITICAL) — Only 9.26% covered (43/464 statements)
• src/enclave/runtime-preflight.ts — 70% covered, partial branch coverage
• Multiple service modules reached 100% coverage in this cycle
• Log parsing modules (log-parser.ts, log-aggregator.ts) now at 97%+ coverage

---

🔎 Notable Findings

1. Critical Gap in Bounded Execution Module

   • finite-disclosure.ts has 9.26% statement coverage (only 43 of 464 statements covered)
   • 0.26% branch coverage indicates most conditional paths are untested
   • This file handles critical information disclosure controls — test coverage is inadequate
   • Action: High-priority test expansion needed before production rollout

2. Enclave Runtime Preflight Under-Tested

   • runtime-preflight.ts at 70% coverage with only 46.51% branch coverage
   • Several runtime validation scenarios are missing test cases
   • Affects enclave startup safety and readiness probes
   • Action: Add tests for error conditions and timeout scenarios

3. Strong Core Security Coverage

   • All L3/L4 network rules (iptables) and L7 filtering (Squid) at 100% statement coverage
   • Domain pattern matching and validation 100% covered
   • Container lifecycle management 96.62% covered
   • Result: Network isolation layer is well-tested

4. Branch Coverage Opportunity

   • While statement coverage is strong (93%), branch coverage (86%) shows conditional logic gaps
   • Primarily in error handling paths and edge-case branches
   • Examples: api-proxy-service.ts (97% stmts, 92.3% branches), firecracker/api-client.ts (84.41% stmts, 68.96% branches)

🎯 Recommendations

HIGH PRIORITY

1. Expand Bounded Execution Tests
   • Target: Increase finite-disclosure.ts from 9.26% to 80%+ statement coverage
   • Scope: Add test cases for information disclosure scenarios, boundary conditions, and error paths
   • Effort: ~2–3 hours (374 statements to cover)
   • Impact: Closes critical security-functionality gap

MEDIUM PRIORITY

2. Improve Enclave Runtime Safety

   • Target: Increase runtime-preflight.ts from 70% to 90%+ statement coverage
   • Scope: Test startup timeouts, health check failures, and recovery paths
   • Effort: ~1–2 hours
   • Impact: Ensures reliable enclave startup and failure diagnosis

3. Branch Coverage for Error Paths

   • Target: Increase branch coverage from 86.28% to 90%+ across core modules
   • Scope: Add tests for exception handling in firecracker/api-client.ts, enclave/manager.ts, enclave/staging.ts
   • Effort: ~3–4 hours
   • Impact: Improves reliability in error scenarios and edge cases

LOW PRIORITY

4. Polish Remaining Edge Cases
   • Files at 80–95% coverage (e.g., commands/build-config.ts at 90.38%) benefit from targeted branch tests
   • No blocking issues, but improves robustness
   • Effort: ~2 hours per file
   • Impact: Incremental reliability improvement
