99-111: Consider enhancing serialization test robustnessWhile the current tests cover the happy path well, consider:
- Adding explicit error handling instead of using
unwrap()- Adding negative test cases to verify serialization behavior with edge cases
Example improvement:
#[test] fn serialize_message_model_with_error_handling() { let model = MessageModel::Broadcasting; let result = serde_json::to_string(&model); assert!(result.is_ok()); assert_eq!(result.unwrap(), "\"BROADCASTING\""); }
113-132: Consider adding more deserialization error casesThe current tests cover basic scenarios well. Consider adding tests for:
- Empty string
- Null value
- Numeric values
- Malformed JSON
Example additions:
#[test] fn deserialize_message_model_edge_cases() { // Empty string assert!(serde_json::from_str::<MessageModel>("\"\"").is_err()); // Null assert!(serde_json::from_str::<MessageModel>("null").is_err()); // Number assert!(serde_json::from_str::<MessageModel>("123").is_err()); // Malformed JSON assert!(serde_json::from_str::<MessageModel>("{invalid}").is_err()); }
134-144: Consider adding consistency tests between Display and SerializeThe Display tests are good, but consider adding tests to ensure consistency between Display and Serialize implementations.
Example addition:
#[test] fn verify_display_matches_serialization() { let model = MessageModel::Broadcasting; let displayed = model.to_string(); let serialized = serde_json::to_string(&model).unwrap(); assert_eq!(format!("\"{}\"", displayed), serialized); }

93-98: LGTM! Test module structure follows best practices
The test module is properly configured with appropriate imports and module organization.
93-145: Overall test implementation looks great! 🎉
The test suite provides good coverage of the MessageModel functionality:
- ✅ Serialization for both variants
- ✅ Deserialization including error cases
- ✅ Display trait implementation
- ✅ Clear and maintainable test structure
While I've suggested some potential enhancements, the current implementation satisfactorily fulfills the requirements of issue #1330.

93-97: LGTM! Test module setup is correct.The test module is properly configured with the
#[cfg(test)]attribute and necessary imports.Consider grouping imports by adding a blank line between external crate imports (
serde_json) and internal imports (super::*).
99-111: Consider adding a test for custom serialization format.The current tests cover basic serialization well, but consider adding a test using a custom serializer format (like pretty-printed JSON) to ensure the serialization works correctly in different contexts.
Here's a suggested additional test:
#[test] fn serialize_message_model_pretty() { let model = MessageModel::Broadcasting; let serialized = serde_json::to_string_pretty(&model).unwrap(); assert_eq!(serialized, "\"BROADCASTING\""); }
93-145: Overall test coverage is good with room for enhancement.The test suite effectively covers the core functionality of MessageModel:
✓ Serialization
✓ Deserialization
✓ Display formatting
✓ Error handlingConsider adding property-based tests using a framework like
proptestto more thoroughly test the serialization/deserialization roundtrip property:#[test] fn roundtrip_message_model() { let models = vec![MessageModel::Broadcasting, MessageModel::Clustering]; for model in models { let serialized = serde_json::to_string(&model).unwrap(); let deserialized: MessageModel = serde_json::from_str(&serialized).unwrap(); assert_eq!(model, deserialized); } }

134-144: LGTM! Display tests are comprehensive.
The display tests properly verify the string representation of both MessageModel variants.

🛠️ Refactor suggestion
Add tests for case sensitivity and whitespace handling.
While the current deserialization tests are good, consider adding tests for:
- Case sensitivity (e.g., "broadcasting" vs "BROADCASTING")
- Whitespace handling (e.g., " BROADCASTING ")
Here are the suggested additional tests:
#[test]
fn deserialize_message_model_case_insensitive() {
let json = "\"broadcasting\"";
let deserialized: Result<MessageModel, _> = serde_json::from_str(json);
assert!(deserialized.is_err());
}
#[test]
fn deserialize_message_model_whitespace() {
let json = "\" BROADCASTING \"";
let deserialized: Result<MessageModel, _> = serde_json::from_str(json);
assert!(deserialized.is_err());
}
