During October 2024, this developer focused on stabilizing UI test automation for tax submission flows by addressing critical issues in two repositories, hmrc/income-tax-submission-journey-tests and hmrc/income-tax-self-employment-frontend. Using Scala and leveraging skills in backend development and test automation, they resolved intermittent browser failures by upgrading the ui-test-runner and corrected cache clearing by fixing URL composition for the clearDatabase endpoint. These targeted bug fixes improved test determinism and accelerated CI feedback, enabling more reliable validation for development and QA teams. Their disciplined approach emphasized single-purpose commits and minimal risk, contributing to more stable and maintainable automated testing pipelines.
