Tagging in ScalaTest

Really useful for separating tests running in different CI builds.

I usually define a tags.scala which contains the tag definitions:

package com.ojha

import org.scalatest.Tag

object UnitTest extends Tag("com.ojha.UnitTest")

object IntegrationTest extends Tag("com.ojha.IntegrationTest")

Then tag tests like this:

it should "be a cat" taggedAs UnitTest in {
  
}

Then from the sbt console to run only the unit tests:

"test-only -- -n com.ojha.UnitTest"

To run everything except integration tests:

"test-only -- -l com.ojha.IntegrationTest"
