intellij Junit generate test classes for scala

Hi I am using scala with Junit.
Every time I want to generate a test class CTRL + SHIFT + T it always generates a java class and I always need to reformat the class and the code inside it.
How can I implement this feature in Intellij? I'd like to generate a test class like this:

    package combiner.impl

import org.junit.Test;


import org.junit.Assert._

class NextploraWeboDataFrameCombinerImplTest {

  @Test
  def combineDataFrames() {
  }
}
