# Extractor Implementation Tests

This directory contains comprehensive tests for the Extractor implementations, focusing on the improvements made to resource management, error handling, and input validation.

## 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)
