A simple sbt 0.13.x plugin that sends native OS notifications when tests are completed. Uses Toast notifications on Windows (tested on Windows 10), Notification Center on Mac OS X (tested on Mac OS X Yosemite) and libnotify on Linux (requires libnotify-bin package, tested on Ubuntu with Gnome).

Add the following to ./project/plugins.sbt

addSbtPlugin("me.penkov" % "sbt-notifications" % "0.0.2")

To receive notifications only when tests failed use

notifyFailureOnly := true

in build definition.
