🔍 Notable Findings

1. Low Branch Coverage in Core CLI Entry Points

Impact: Medium
Files: cli.ts (50% branches), network-options.ts (50% branches)

The main CLI entry point (cli.ts) has only 1 of 2 branches covered. This is a thin orchestration layer (7 statements total), but the uncovered branch likely involves the require.main === module check for direct execution vs. module import scenarios.

Gap: Error paths in option validation functions (validateNetworkOptions) are not fully exercised.

2. Validator Module Branch Coverage

Impact: Medium
Files: config-assembly.ts (65.33% branches), config-writer.ts (65.51% branches), log-parser.ts (65.62% branches)

The validator modules in src/commands/validators/ have comprehensive statement coverage (81%+) but miss many conditional branches. These are likely error-handling paths for invalid input configurations.

Gap: Missing test cases for:

• Invalid configuration combinations in assembleAndValidateConfig()
• Edge cases in DNS server validation
• Malformed log entries in log-parser.ts

3. Recent Major Refactor — Strong Test Coverage

Impact: Positive
Files: Entire src/commands/ directory (added in commit 7a64531)

A major CLI refactoring was completed in the last 7 days, moving orchestration logic from a monolithic src/cli.ts into modular command handlers. Despite being brand new code:

• All new command modules have 85%+ statement coverage
• Test files were added alongside implementation files
• No security-critical paths were compromised

This demonstrates excellent test discipline during active development.

4. Test Helper Utilities Have Low Branch Coverage

Impact: Low
Files: docker-test-fixtures.test-utils.ts (40% branches)

Test utility modules have lower branch coverage, which is acceptable since they are not production code. However, ensuring test helpers are robust prevents flaky tests.

📈 Recommendations

High Priority (Security / Robustness)

1. Add error path tests for validator modules

   • Files: config-assembly.ts, network-options.ts, log-parser.ts
   • Focus: Test invalid inputs, malformed configurations, edge cases
   • Expected improvement: Branch coverage from 50–65% → 85%+

2. Cover audit enricher error scenarios

   • File: audit-enricher.ts (74.13% branches)
   • Focus: Test log parsing failures, missing fields, malformed timestamps
   • Expected improvement: Branch coverage from 74% → 90%+

Medium Priority (Maintainability)

3. Improve branch coverage in configuration writers

   • Files: config-writer.ts (65.51% branches), cli-workflow.ts (85.71% branches)
   • Focus: Test error paths in file write operations, permission errors
   • Expected improvement: Branch coverage from 65–85% → 90%+

4. Add edge case tests for host path prefix translation

   • File: host-path-prefix.ts (75% branches)
   • Focus: Test DinD path translation edge cases, invalid prefix formats
   • Expected improvement: Branch coverage from 75% → 90%+

Low Priority (Nice-to-Have)

5. Improve test helper robustness
   • Files: docker-test-fixtures.test-utils.ts (40% branches)
   • Focus: Ensure test utilities handle edge cases to prevent flaky tests
   • Expected improvement: Branch coverage from 40% → 70%+
