# 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)

   *
   * There is no mechanism to remove an event listener. Implementations should instead ignore events
   * that they are not interested in.
   *
   * @see EventListener for semantics and restrictions on listener implementations.

### Key Design Patterns

**Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection
**Strategy**: `CrawlerClient`, `Extractor`, `Transformer` - pluggable implementations
**Builder**: `RequestDataBuilder`, `ExtractorBuilder` - fluent construction
**Template Method**: `AbstractCrawlerClient`, `AbstractExtractor` - common logic with overrides

   * be thread-safe.
