John Haleyrequested to merge
feature/core-security-coverage into main

Summary

  • Implements comprehensive security test coverage for core.ts to address critical security vulnerability (Issue #29 (closed))
  • Achieves 87.69% statement coverage (up from 28%) and 100% function coverage
  • Tests 31 critical security scenarios including token sanitization, input validation, and URL encoding

Test Coverage Achievements

  • Statements: 87.69% (target: 80%+) ✅
  • Functions: 100% (target: 80%+) ✅
  • Security-Critical Functions: All covered with comprehensive edge cases

Security Test Areas Covered

🔒 Token Security & Sanitization

  • Bearer token redaction from error messages
  • Personal access token sanitization in logs
  • Token leakage prevention in stack traces
  • Environment variable security validation

🛡️ Input Validation & Sanitization

  • Project ID validation and encoding
  • Branch name special character handling
  • File path traversal prevention
  • URL encoding security

🌐 HTTP Client Security

  • Request/response header sanitization
  • Error message security filtering
  • API URL validation and normalization
  • Authentication header security

🔍 Git Repository Detection

  • Repository path validation
  • Remote URL parsing security
  • Git configuration access control
  • Directory traversal prevention

Quality Gates Status

  • ✅ TypeScript compilation passes
  • ✅ ESLint security rules enforced
  • ✅ Prettier formatting applied
  • ✅ All 31 security tests passing
  • ✅ Coverage thresholds exceeded

Security Impact

This addresses a critical security vulnerability where core authentication and validation functions had insufficient test coverage (28%), leaving potential attack vectors undetected.

Files Modified:

  • tests/unit/core-security.test.ts (new) - Comprehensive security test suite
  • eslint.config.js (updated) - Test-specific ESLint configuration

Resolves: Issue #29 (closed) (core.ts has dangerously low 28% test coverage)
