在Eclipse中没有运行方式-> Scala测试？

Question

I recently re-installed my OS from scratch (Debian). Then did following:

• Installed Scala from the repository
• Installed Eclipse Kepler from the repository
• Installed Scala IDE from inside Eclipse
• created a Scala class
• created a Scala test which makes a new instance of my class
• copied the scalatest jar into the project and added it to the build path

Here, I noticed that I don't have "Run as -> Scala test" in the menu. Looked at the versions and noticed that I have installed a Scala IDE which is made for Scala 2.10, but I have 2.10 installed. The Eclipse version 3.8 was correct.

So I uninstalled the repository scala, downloaded 2.10.4 and installed it manually, setting both $SCALA_HOME and $PATH. I restarted the computer in case Eclipse has loaded some dependencies to the old scala, and tried running the test again. But to no avail; I have the choice to run a scala application, but not a scala test.

My mini-test is extremely simple and doesn't reference anything unusual:

import org.scalatest._
import Matchers._

class StudySpec extends FlatSpec {
  "It" should "be possible to create a new Study with the default constructor." in {
    val newStudy = new Study()
  }

What did I do wrong, and how can I get the test to run?

Seems you haven't Install the ScalaTest plugin for Scala IDE . Just install it.
