### Testing

**Structure**: `src/test/java/org/codelibs/fess/crawler/`
**Frameworks**: JUnit 4, UTFlute, Mockito, Testcontainers
**Test Resources**: `src/test/resources/`

**Pattern**:
```java
public class MyTest extends UTFlute {
    @Override
    protected void setUp() throws Exception {
        super.setUp();
        // Setup
    }

- Ensure all property values are properly escaped
- Run `mvn clean` before rebuilding
