During January 2025, contributed a targeted feature enhancement to the onecx/onecx-portal-ui-libs repository by implementing ID-based filtering for DivHarness components. This work introduced DivHarnessFilters.id and HarnessPredicate.getId, enabling precise selection of div elements by their ID within Angular testing environments. The approach focused on improving test reliability and maintainability by allowing more granular and robust targeting of UI elements during automated tests. Utilizing TypeScript and leveraging expertise in Angular Testing and Component Harnesses, the developer updated tests and documentation, collaborated through code reviews, and ensured seamless CI integration, delivering a focused improvement without addressing bug fixes during this period.
