How to configure sbt test / ScalaTest to only show failures?
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, and the green text from the successful unit tests makes it difficult to focus on just the failures.
Example of what I'm talking about:
[info] - should have colors
[info] - should not be dead
//.... x 100
[info] - animals should not be rainbows *** FAILED ***
[info] -"[rainbow]s" was not equal to "[ponie]s" (HappinessSpec.scala:31)
What I would like is something that just shows the failure(s):
[info] - animals should not be rainbows *** FAILED ***
[info] -"[rainbow]s" was not equal to "[ponie]s" (HappinessSpec.scala:31)
I realize there is the test-quick sbt command, but it's still running 300 successful unit tests in my case when there are only 30 failures.
Something along the lines of this in terms of usage is what I'm looking for:
sbt> ~ test -showOnlyFailures
I would also be happy with something that shows all of the failures at the end of running the unit tests. IIRC, this is how RSpec works in Ruby...
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
对于那些使用maven和scalatest-maven插件的人，你可以添加这个配置：
<configuration>
<stdout>I</stdout>
</configuration>
You could try the sbt command
last-grep error test
This should show you the errors/failures only.
