PR Summary

Changes Introduced:

1. Cache Tests Enhancements:

   • Replaced manual checks with assert statements from testify for better readability and maintainability.

   • Added validation for cache expiration behavior after the specified duration.

   • Improved test coverage for cache deletion scenarios.

2. DeepCopy Function Tests:

   • Added comprehensive test cases for the DeepCopy function:

     • Simple Structs: Validates copying of basic fields.

     • Nested Structs: Ensures deep copying of nested fields and pointer values.

     • Nil Values: Confirms behavior when source struct contains nil values.

     • Error Handling: Validates behavior when incompatible types are passed.

Benefits:

• Improved test reliability and clarity using testify assertions.

• Enhanced test coverage for both caching and deep copy functionalities.

• Ensures robustness of the DeepCopy function across various edge cases.

Coverage
