What a Slink.Testing.run/3 observed.
:result— the handler's raw return value (:ok,{:reply, …},{:ack, …}, …). The reply, if any, was also performed and captured.:calls— Web API calls, in order, as{method, params}tuples. The params' top-level keys are atoms (e.g.{"chat.postMessage", %{channel: "C123", …}}); nested maps keep whatever keys the handler built them with.:responses— bodies posted to aresponse_url(slash replies,update_original/3), in order.
