### Custom Content Extractor

```java
public class CustomExtractor extends AbstractExtractor {
    @Override
    public ExtractData getText(final InputStream inputStream, final Map<String, String> params) {
        // Custom extraction logic
        ExtractData extractData = new ExtractData();
        // ... implementation
        return extractData;
    }
}

        }

        @Test
        void testGetInputStream() throws IOException {
            // Act
            var inputStream = smbFile.getInputStream();

            // Assert
            assertNotNull(inputStream);
            verify(smbFile).openUnshared(0, // SmbConstants.O_RDONLY = 0x01, but SmbFileInputStream uses 0

- ✅ Validates non-null streams
- ✅ Throws CrawlerSystemException for null
- ✅ Called during getText execution
- ✅ Does not consume or modify stream
- ✅ Consistent behavior across multiple calls
- ✅ Works with various InputStream types

### 5. TextExtractorEnhancedTest.java
**Purpose**: Test TextExtractor improvements and encoding handling.

**Key Test Areas**:
- Improved error messages with encoding
