Worked on expanding automated test coverage for the ApryseSDK/PDFNetWrappers repository, focusing on the reliability of font-related API usage. Developed and integrated a targeted test within the PDFUATest suite to exercise the GetSystemFontList() function, ensuring system font retrieval is validated during continuous integration runs. This PHP-based solution was incorporated into the existing test harness, providing automated execution and improved regression safety for font list functionality. The work emphasized sustainable quality gates for future development and laid the foundation for broader API coverage. Technical skills applied included PHP development and software testing, with a focus on maintainable, CI-friendly test design.
