cljs.test is part of core now so we should support it. There is a neat solution here for running the tests after each recompile using phantomjs, which I think is a good idea:

I think cljsbuild-ui should display this, not through the :notify-command config as shown above, but by parsing cljsbuild's :test-commands so the user can setup different tests, which they can enable from the UI like they enable builds. Running the tests should be done after each recompile as well.
