Scaffolds Jest tests for Adobe App Builder actions and React Spectrum components, with ready-made templates for unit, integration, and component tests. It knows how to mock State, Files, Events SDKs and the ExC Shell context, so you're not reinventing test fixtures every time. The fast-path workflow is smart: say "test my action" and it reads your source, picks the right template, injects mocks for detected dependencies, and generates tests that cover success, bad input, and error cases. Component tests automatically wrap everything in Provider with theme props because Spectrum renders nothing without it. Good for teams that want consistent test patterns across App Builder projects without arguing about Jest setup every sprint.
