Worked on the PowerShell/PowerShell repository to enhance the reliability and clarity of validation error messaging. Focused on resolving a bug where ValidateLength error messages did not consistently reflect the expected input lengths, improving user feedback and reducing ambiguity. Refactored validation tests to use more descriptive function names, which increased readability and maintainability of the test suite. Updated test cases to verify that error messages accurately communicate length requirements, supporting easier maintenance and fewer support escalations. Utilized PowerShell scripting, error handling, and testing best practices to deliver a more robust and CI-ready validation framework within the PowerShell codebase.
