test-slack-app

Use when a developer wants to test, try out, smoke-test, verify, or confirm that a Slack app built with the Slack CLI (or a plain Bolt app) actually works, by running it in a developer sandbox or a Free Team, never a workspace with real users, with slack run and exercising its real slash commands, shortcuts, events, actions, modals, App Home, and assistant surfaces. Also covers slack doctor and slack manifest validate health checks before hands-on testing.
