QA Instructions, Screenshots, Recordings

Testing the Document Cache

1. Run the document cache tests:

python -m unittest tests/test_document_cache.py

2. Run the comprehensive tests to validate cache performance:

python -m tests.test_scripts.test_comprehensive

3. Verify cache performance improvements in the generated report at
   tests/test_results/comprehensive_test.json

Testing Error Handling

1. Test error handling with intentionally problematic files:

# Test with a damaged PDF
python -m tests.test_scripts.test_error_handling tests/test_data/damaged.pdf

# Test with a damaged PPTX
python -m tests.test_scripts.test_error_handling tests/test_data/damaged.pptx

Added/updated tests?

• Yes
• No, and this is why: please explain why tests are not included

Added comprehensive test suite including:

• Unit tests for document cache operations
• Performance tests for all document types
• Memory profiling for large document processing
• Cache hit/miss rate verification
• Error handling validation
