Using Specs2 in a Typesafe activator play application - scala

Question

I have used specs2 many times successfully in vanilla SBT projects. now I am starting to learn typesafe activator platform.
I did the following steps
activator new Shop just-play-scala
this is my build.sbt file
name := """Shop"""
version := "1.0-SNAPSHOT"
// Read here for optional jars and dependencies
libraryDependencies ++= Seq("org.specs2" %% "specs2-core" % "3.6.1" % "test")
resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"
scalacOptions in Test ++= Seq("-Yrangepos")
lazy val root = project.in(file(".")).enablePlugins(PlayScala)
I created a file Shop/app/test/models/ShopSpec.scala
import org.specs2.mutable.Specification
class ShopSpec extends Specification {
def foo = s2"""
| This is a specification to check the 'Hello world' string
| The 'Hello world' string should
| contain 11 characters $e1
| start with 'Hello' $e2
| end with 'world' $e3
| """.stripMargin
def e1 = "Hello world" must haveSize(11)
def e2 = "Hello world" must startWith("Hello")
def e3 = "Hello world" must endWith("world")
}
When I run activator test I get an error
[success] Total time: 0 s, completed Jun 24, 2015 12:21:32 AM

I have previously written spec2 test cases successfully when I was using SBT projects. but only when I use the typesafe activator that I get this issue with test cases.
I even changed the code of my test to something as simple as
import org.specs2.mutable.Specification
class ShopSpec extends Specification {
"A shop " should {
"create item" in {
failure
}
}
}
But still the same problem.

Answer 1

Wait .. I think I resolved it.
The activator play platform already has specs2 included so there is no need for me to tweak the built.sbt file for specs 2.
So I removed everything I had added to build.sbt file and left the file as
name := """Shop"""
version := "1.0-SNAPSHOT"
lazy val root = project.in(file(".")).enablePlugins(PlayScala)
Now it works fine. So basically, I don't need to add anything in a activator project for specs2.
I could have deleted the question... but leaving it here so that it can be of help to someone.

What worked for me was adding the following to build.sbt:
libraryDependencies ++= Seq("org.specs2" %% "specs2-core" % "3.6.2" % "test",
"org.specs2" %% "specs2-junit" % "3.6.2" % "test")
