## Test Files Overview

### 1. ExtractorResourceManagementTest.java
**Purpose**: Verify proper resource management in Extractor implementations.

**Key Test Areas**:
- Resource closure on successful extraction (MS Office extractors)
- Resource closure on failed extraction
- Improved error messages with context
- Input validation using `validateInputStream()`

**Covered Extractors**:
- MsWordExtractor
- MsExcelExtractor
