How to configure sbt test / ScalaTest to only show failures?

Question

Is there a way to truncate the test results to only show result text for unit tests only when the unit test has failed? I\'m working on a Scala project that has 850 unit tests,

Answer 1

After adding the following to build.sbt, scalaTest will show a fail summary after the standart report:

testOptions in Test += Tests.Argument("-oI") 

I - show reminder of failed and canceled tests without stack traces
T - show reminder of failed and canceled tests with short stack traces
G - show reminder of failed and canceled tests with full stack traces

There is also a "drop TestSucceeded events" flag, but I have failed to use it: http://www.scalatest.org/user_guide/using_the_runner
