[FEATURE] Enhance input data validation for unit tests

[purplesmoke05]

Is your feature request related to a problem? Please describe.

• Currently, our unit tests that target processing logic with multiple data states as input lack comprehensive coverage of possible data variations.
• The existing tests don't sufficiently validate all edge cases and combinations of input states, which creates potential blind spots in our test coverage.
• This inadequate validation increases the risk of undetected bugs when data patterns fall outside our current test scenarios.

Describe the solution you'd like

• Implement enhanced input data validation for unit tests by increasing the variety of test data and creating a systematic approach to ensure comprehensive coverage.
• Consider ways to verify data completeness across our test suite and identify gaps.
