Suppress successes in Play! framework test runner

Suppress successes in Play! framework test runner

Running play test is spammy.
How can I configure it to, by default, only show when tests fail, and then
give a summary of a number of passed.
In Build.scala I've tried various permutations of...
testOptions in Test += Tests.Argument("-oq", "junitxml", "console")
// or
testOptions in Test += Tests.Argument("-oS", "junitxml", "console")
but none of them seem to work. How can this be accomplished?
