May 2025: Delivered targeted frontend enhancements for two HMRC CRS FATCA projects, delivering business value through more reliable test data, robust enrolment workflows, and maintainable code. Key outcomes include: - Improved Scala Generators with nonEmptyString utility in hmrc/crs-fatca-fi-management-frontend, reducing repetitive code and increasing consistency across generator definitions. Commit: ea5bfac64ebc27d27560c9c344c38c78ae0d630d (DAC6-3672: Refactor generators to use nonEmptyString (#239)). - Hardened test data generation in hmrc/crs-fatca-registration-frontend by adopting nonEmptyString-based generators, boosting reliability for test data across models (e.g., contact names, addresses). Commit: 34c072396389cd311a24a0b529ab9ba0dce3de5b (DAC6-3672: Refactor string generators (#231)). - Introduced Group Enrolment Flow in registration-frontend, with EnrolmentResponse model, robust enrolment checks, improved error handling, concurrent group checks, and updated IdentifierAction to include group information and redirect behavior for already-enrolled users. Commit: ed6167c0f904383142c8e331259468997c25c2b2 (DAC6-3546: Add EnrolmentResponse model (#230)). Overall, these changes reduce test flakiness, enhance onboarding flows for group enrolment, and improve maintainability and code quality across the FATCA frontend suite.
