How to have SBT re-run only failed tests

Is there a way to have SBT re-run only the tests that have failed in the last run of the test suite? For example, if I run sbt test and 3 out of the 20 tests I run fail, is there any command I can run to have SBT just re-run those 3 tests that fail?

Specifically I am using Scala Test and Scala Check for the tests I am running through SBT.

Try test-quick scala-sbt.org/0.12.4/docs/Detailed-Topics/… – maks
That seems to work for the ScalaCheck tests, but not for the Scala Test tests. – Christopher Wells
Actually, I tried it again and noticed that it rather just ignores all of the ScalaCheck test event the ones the fail. – Christopher Wells

If you are using the latest version of sbt simply run sbt testQuick.
