Johnny developed comprehensive end-to-end test coverage for the UCSB Organizations module in the ucsb-cs156-s25/team02-s25-16 repository. Focusing on role-based access control, Johnny implemented tests using Java, JUnit, and Playwright to ensure that only administrators could create, edit, or delete organizations, while regular users were restricted from these actions. The test suite validated UI flows and enforced correct permission boundaries, directly supporting regression safety and reducing production risk. By automating these organization management scenarios within a Spring Boot application, Johnny’s work accelerated QA feedback cycles and improved confidence in the module’s security and user experience, though the scope was limited.
