A Generic Verification Utility Class in Java for Automated Testing

In the process of automation, many validation points are encountered; this article presents a generic verification class in Java that consolidates common validation functions, including code checking, value retrieval, containment checks, numeric and boolean validation, array and JSON detection, and regex matching, along with a utility to parse JSON into line lists.
