Implement Tests for "Get info/refs" Endpoint #65

To ensure the reliability and functionality of the "Get info/refs" endpoint in our custom Git server, we need to develop a comprehensive suite of tests. These tests will validate the endpoint's behavior under various scenarios, including both typical use cases and edge cases.

Objective:
The primary goal is to ensure that the "Get info/refs" endpoint accurately provides Git references to clients in a manner that supports Git operations such as clone and fetch, adhering to Git's protocol specifications.

Acceptance Criteria:

• Tests should cover successful requests, verifying that the endpoint returns the correct Git references.
• Include tests for error handling, such as invalid requests or server errors, to ensure the endpoint responds appropriately.
• Tests for scalability and performance, ensuring that the endpoint can handle a high volume of requests without degradation in service.
• Ensure that tests are automated and integrated into our CI/CD pipeline for continuous validation during development cycles.

Additional Notes:

• Consider mock objects or services to simulate interactions with the underlying Git repository, allowing for isolated testing of the endpoint logic.
• Document any setup or configuration necessary for running the tests, ensuring that other developers can easily execute them.
