## Start an Application Without Certain States
Whether it is in REPL or during testing, it is often useful to start an application _without_ certain states. These can be queue listeners that are not needed at REPL time, or a subset of an application to test.
The `start-without` function can do just that:
```clojure
(mount/start-without #'app.feeds/feed-listener
#'app/nrepl)
```
which will start an application without starting `feed-listener` and `nrepl` states.
Here is an [example](test/check/without_test.clj) test that excludes Datomic connection and nREPL from an application on start.
