something like this then?

```clj
(deftest "Creates org with default custom key and adds new system"
  (with-unique [org (kt/newOrganization {:name (uniqueify "defaultsysinfo")})
                env (kt/newEnvironment {:name "dev" :org org})
                system (kt/newSystem {:name "sys" :sockets "1" :system-arch "x86_64" :env env})]
    (let [org (assoc org :initial-env env)]
      (ui/create-all (list org env system))
      (org/add-custom-keyname org "Manager")
      (browser click :katello.systems/custom-info)
      (assert/is (browser isTextPresent "Manager")))))
```
