Mahja Sarschar developed an ID-based filtering enhancement for DivHarness in the onecx/onecx-portal-ui-libs repository, focusing on improving Angular component testing workflows. By introducing DivHarnessFilters.id and HarnessPredicate.getId, Mahja enabled precise selection of div elements by their ID, which increased the reliability and maintainability of UI harness tests. The work was implemented in TypeScript and leveraged expertise in Angular Testing and Component Harnesses. Mahja collaborated through code reviews, updated documentation, and ensured CI integration. Although the scope was limited to a single feature over one month, the solution addressed targeted test selection and contributed to more robust automated test coverage.
