## Contributing

When adding new tests:
1. Follow the existing naming convention: `test_<method>_<scenario>_<expectedResult>`
2. Add clear JavaDoc comments explaining the test purpose
3. Ensure tests are independent and can run in any order
4. Clean up resources in finally blocks or use try-with-resources

        // Ensure no unexpected extra options
        assertEquals(3, returned.size(), "Only provided options are expected");
