Enhance Unit Test Coverage: Tracking Issue

[asddongmen]

Background

The current project’s unit test coverage has not met the expected target, with insufficient test coverage for some critical modules and edge cases. To improve code quality and system reliability, we need to systematically enhance unit test coverage.

Goals

• Increase unit test coverage to over 80%.

• Ensure that all core functionalities and edge cases are covered by corresponding test cases.

• Identify and supplement missing tests in the existing codebase.

Packages

• dynstream tests: Add unit test for DS #756 [83%]
