- `validateInputStream()` method behavior
- Exception types and messages
- Stream consumption (should not consume)
- Consistency across multiple calls

**Test Count**: 11 tests

**Key Scenarios**:
- ✅ 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

        assertDoesNotThrow(() -> outputStream.write(data, 5, 5)); // valid - will consume second mock (5)
    }
