Testing expectations

app has an end-to-end test suite under app/tests/e2e that exercises the built CLI across setup, check, download, verify, progress, version, and REPL flows.

When you add a new command or change command behavior, update or add E2E tests for the user-visible behavior. See E2E testing flow for a full guide.
