Jack Hellowell developed and enhanced core testing frameworks for the NHSDigital/personal-demographics-service-api repository, focusing on robust API development and backend test automation. He built a generic patch request testing framework for patient data updates, centralizing patch body generation and refactoring existing tests to improve reliability and reduce duplication. Jack also introduced sandbox testing capabilities, enabling isolated creation of test patients and stubs to streamline local development. His work leveraged Java, JavaScript, and Cucumber/Gherkin, applying behavior-driven development principles to expand test coverage and clarify API operations. These contributions improved data integrity, accelerated deployment cycles, and enhanced maintainability across the codebase.
