Hilary Martin developed a comprehensive suite of automated test scenarios for the NHSDigital/bcss-playwright repository, focusing on expanding coverage for core application functionalities. Using Playwright and Python, Hilary designed and implemented tests that simulate user actions such as viewing contacts, creating and editing analysers, setting invitation rates, and verifying communication types for GP practices. This work enhanced the reliability of the continuous integration feedback loop by enabling earlier detection of regressions and ensuring consistent application behavior before releases. The effort prioritized quality assurance and test design, providing traceability and supporting knowledge transfer, though it did not involve direct bug fixes during this period.
