Summary

This PR adds comprehensive test coverage to achieve the 80% coverage target, improving from 74% to 80.68%.

Note: This PR contains only the test code changes. The CI/CD coverage threshold updates (74% → 80%) were handled separately in PR #12 via the ci-cd-maintenance branch, following proper branch strategy.

What's Changed

✨ New Test Coverage

  • 24 comprehensive test cases covering previously untested code paths
  • Security validation tests for XML entity attacks and JSON recursion bombs
  • Error handling tests for edge cases and malformed inputs
  • Utility function tests for text extraction and data validation

📊 Coverage Results

  • Before: 74.25% coverage
  • After: 80.68% coverage (exceeds 80% target)
  • Tests: 102 total tests (up from 78)

Test Categories Added

Security Validation

  • XML entity attack prevention
  • JSON recursion bomb detection
  • Base64 validation and size limits
  • File content security checks

Error Handling

  • Timeout and exception handling
  • Invalid input processing
  • Encoding fallback mechanisms
  • Binary content extraction

Utility Functions

  • Unicode text sanitization
  • File validation helpers
  • Content type detection
  • Safe conversion limits

Quality Assurance

  • ✅ All 102 tests pass
  • ✅ 80.68% coverage meets quality gate (thresholds updated in PR Ci cd maintenance #12)
  • ✅ No linting issues
  • ✅ Type checking passes
  • ✅ Security scans clean

Branch Strategy

This follows the documented branch strategy:

  • CI/CD changes (coverage thresholds) → ci-cd-maintenance branch (PR Ci cd maintenance #12) ✅
  • Test code changes → feature branch (this PR) ✅

Impact

This achieves the coverage quality gate through comprehensive testing of security-critical and error-handling code paths, rather than lowering thresholds.
