Hello folks! I would very much appreciate an advice on how to programatically test routing and, most of all, content type negotiation and coercion. I have generated a new Luminus app with +service, which uses swagger, retit, muuntaja etc. This is what I am trying to do, in the generated myapp.handler:

(do
    (require '[jsonista.core :as json])
    (import java.io.ByteArrayInputStream)
    ((app)
     {:headers {"accept" "application/json"}
      :uri "/api/employee/start"
      :request-method :post
      #_:query-string
      :body (ByteArrayInputStream.
              (json/write-value-as-bytes
                {:first-name "Bo"}))}))
