test: add unit tests for DeviceCodeOAuthFlow

[neo1027144-creator]

Add unit tests for DeviceCodeOAuthFlow record class.

Test cases:

• Construction with all fields populated
• Null refreshUrl (optional field)
• Empty scopes map
• Null validation for required fields (deviceAuthorizationUrl, tokenUrl, scopes)
• Record equality and hashCode consistency

Follows the same testing patterns as FileWithBytesTest.

Fixes #607

Summary of Changes

Hello, 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 significantly improves the robustness of the DeviceCodeOAuthFlow record by introducing a dedicated suite of unit tests. These tests validate the record's behavior across various construction scenarios, ensuring correct handling of both required and optional fields, proper null validation, and consistent equals and hashCode implementations. This work directly contributes to the stability and reliability of the OAuth flow mechanisms.

Highlights

• Unit Test Introduction: Added comprehensive unit tests for the DeviceCodeOAuthFlow record class.
• Test Coverage: Included test cases for full field population, null refreshUrl handling, empty scopes, null validation for required fields (deviceAuthorizationUrl, tokenUrl, scopes), and equals/hashCode consistency.
• Pattern Adherence: Followed established testing patterns, similar to FileWithBytesTest.
• Issue Resolution: Addressed and fixed issue [Bug]: Missing tests for DeviceCodeOAuthFlow #607.

Code Review

This pull request adds a comprehensive set of unit tests for the DeviceCodeOAuthFlow record class. The tests cover construction, null validation for required fields, handling of optional fields, and record equality. The implementation is solid. I've provided a couple of suggestions to make the tests even more robust: one to enhance the assertions in the empty scopes test for better consistency, and another to expand the equality test to include inequality checks, which will provide more complete validation of the record's behavior.

Code Review

This pull request introduces unit tests for the DeviceCodeOAuthFlow class, covering object construction, parameter validation, and basic equality. The feedback suggests enhancing the test suite by adding a test for the immutability of the scopes map to ensure defensive copying and expanding the equality and hash code tests to include more comprehensive edge cases such as type mismatches and null checks.

Code Review

This pull request ensures the immutability of the DeviceCodeOAuthFlow record by implementing a defensive copy of the scopes map during construction. It also introduces a new test class, DeviceCodeOAuthFlowTest, which provides comprehensive coverage for valid and invalid construction scenarios, equality checks, and immutability verification. I have no feedback to provide as no review comments were present.
