Summary of Changes

Hello @NeaguGeorgiana23, 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 focuses on enhancing the robustness of the NoopProvider by adding dedicated unit tests. The tests validate the provider's metadata retrieval and its behavior when evaluating boolean flags, ensuring it consistently returns default values as expected. This change improves the overall quality and reliability of the NoopProvider component.

Highlights

• New Unit Tests: Introduced comprehensive unit tests for the NoopProvider to ensure its correct functionality.
• Metadata Verification: Added a test case to verify that the NoopProvider correctly returns its designated name ('Noop Provider') in its metadata.
• Boolean Evaluation Testing: Implemented tests to confirm that the NoopProvider's boolean flag evaluation consistently returns the provided default value, along with the expected reason, variant, and empty error messages.
• Build System Integration: Integrated the new noop_provider_test into the test/BUILD file, making it part of the project's build and test pipeline.

Code Review

This pull request adds unit tests for the NoopProvider. The changes are good and increase test coverage. I've provided a few suggestions to improve the tests by using parameterized tests to reduce code duplication and to correct an assertion about error messages. I also noted that a couple of files are missing a final newline character.
