Summary of Changes

Hello @ehsavoie, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request serves to undo a previous set of changes that introduced new test cases for the ToProto and FromProto utility classes. The primary impact is the removal of a dedicated test file, FromProtoTest.java, and a specific test method from ToProtoTest.java, effectively streamlining the test suite by rolling back these additions.

Highlights

• Test Reversion: This pull request fully reverts the changes introduced in test: add ToProto and FromProto tests #341, which had added new tests for ToProto and FromProto utilities.
• File Removal: The FromProtoTest.java file, containing tests for FromProto utility methods, has been entirely removed from the codebase.
• Test Case Removal: A specific test case, testToProtoPartUnsupportedType, has been removed from the ToProtoTest.java file.

Code Review

This pull request reverts a previous change, removing tests for ToProto and FromProto utility methods. While the original tests may have had issues, completely removing them is not ideal as it reduces test coverage for ProtoUtils, increasing the risk of future regressions. It would be preferable to fix the tests or replace them to ensure the utility methods are behaving as expected, especially around edge cases like handling unsupported types or malformed inputs.
