How to show only failed test in sbt test?

Question

I have tried command 'sbt "project camera-answer" test' in the console, but too many tests shows, I only want to show failed test. How should I do.

Answer 1

you can run sbt testQuick.

http://www.scala-sbt.org/0.13/docs/Testing.html

also if you use ScalaTest you can add:

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

to your 'build.sbt'.

Answer 2

According to the recent https://www.scalatest.org/user_guide/using_the_runner …

sbt> test -- -oI

-o[…] select the standard output reporter
…
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
