## 7. Testing Strategy

### 7.1 Unit Tests
```java
@Test
public void testRdmaProviderSelection() {
    RdmaProvider provider = RdmaProviderFactory.createProvider("auto");
    assertNotNull(provider);

- ✅ Specific file names in error logs

### 4. Error Messages
- ✅ Encoding information in TextExtractor errors
- ✅ File type context in MS Office errors
- ✅ Archive type in archive extractor errors

## Testing Best Practices

1. **Isolation**: Each test is independent and doesn't affect others
2. **Clarity**: Test names clearly describe what is being tested
3. **Coverage**: Both success and failure paths are tested

 * result extraction, header encoding/decoding, and the round-trip of an
 * encode/decode operation.
