Setting up multiple test folders in an SBT project

Question

We would like to create our SBT project so that we have several test folders, and not one. Therefore, we would like to see:

• root
  • CSI
    • test
      • scala
        • block
        • functional

How do we customize our SBT project file paths for this?

Answer 1

SBT 0.9.x :

(sourceDirectories in Test) := Seq(new File("src/test/scala/unit"), new File("src/test/scala/functional")) 

SBT 0.7.x :

 override def testSourceRoots = ("src" / "test") +++ "scala" +++ ("unit" / "functional")
