}Test 1 failed to catch extra field!
Test 2 (Extra Fields) caught error: Value named 'unknown_field' not used. Remove the rfl::NoExtraFields processor or add rfl::ExtraFields to avoid this error message.
Test 3 (Default) caught error: Field named 'value' not found.
Test 4 Result: Name=OnlyName, Value=42
