Manually exclude some test classes in sbt

Question

I usually do below command in my CI:

clean update compile test publish

However, I'd like to exclude 1 (or a few) test class from the sbt command line.

How can I do this? (I don't want to change my code to use ignore, etc)

Answer 1

Two possible options

1. test-only See http://www.scalatest.org/user_guide/using_scalatest_with_sbt
2. Tags http://www.scalatest.org/user_guide/tagging_your_tests

Answer 2

Just to elaborate on the 2 correct options @Gonfva suggested above:

1. To use testOnly you should run:

   sbt "testOnly org.fully.qualified.domainn.name.ASpec"
   

   When the argument is the FQDN of the class. You can use multiple classes separate them by space. This can be used with glob as well. For example:

   sbt "testOnly *ASpec"
   

2. Using tags. First, define a tag:

   import org.scalatest.Tag
   object CustomTag extends Tag("tagName")
   

   Then, define a test with this tag:

   it should "test1" taggedAs CustomTag in { println("test1") }
   

   Now, in order to include tests using this tag, run:

   sbt "testOnly * -- -n tagName"
   

   Note: * is a wild card. It can be any glob as described in section 1.

   In order to exclude this tag, you need to run:

   sbt "testOnly * -- -l aaa"
