This gets Claude set up to help you test Angular apps with Jest instead of the default Jasmine/Karma combo. It covers the basic installation flow with jest-preset-angular, configuration setup, and the standard TestBed pattern for component tests. Honestly, the migration from Karma to Jest is pretty common now since Jest is faster and has better tooling, so having this context loaded means Claude won't try to give you Karma examples when you're clearly working in a Jest environment. The code snippets are straightforward but they nail the 80% use case of getting a component test running.
