Neil Frost focused on enhancing the security and reliability of the Planning-Inspectorate/back-office repository by addressing vulnerabilities and test instability. He updated the end-to-end testing configuration, applying a security patch to the dotenv dependency and refactoring the Cypress setup to reduce test fragility. Using JavaScript and Cypress, Neil streamlined test assertions and configuration files, which minimized the risk of flaky tests and improved the consistency of test data across environments. His work resulted in a reduced vulnerability surface and more reliable continuous integration feedback, supporting smoother deployments. The changes were targeted, affecting only dependency versions and test-related code.
