Very slow to compile Unit Tests

Hi

I''m running a Scala Unit Test in IDEA 10.5.1, but it's also bad simply running a Java Unit test.

It takes around 13s to run this simple test each time:

import org.scalatest.junit.AssertionsForJUnit
import scala.collection.mutable.ListBuffer
import org.junit.Assert._
import org.junit.Test
import org.junit.Before

class ExampleSuite extends AssertionsForJUnit {

  var sb: StringBuilder = _
  var lb: ListBuffer[String] = _

  @Before def initialize() {
    sb = new StringBuilder("ScalaTest is ")
    lb = new ListBuffer[String]
  }

  @Test def verifyEasy() { // Uses JUnit-style assertions
    sb.append("easy!")
    assertEquals("ScalaTest is easy!", sb.toString)
    assertTrue(lb.isEmpty)
    lb += "sweet"
    try {
      "verbose".charAt(-1)
      fail()
    }
    catch {
      case e: StringIndexOutOfBoundsException => // Expected
    }
  }

  @Test def verifyFun() { // Uses ScalaTest assertions
    sb.append("fun!")
    assert(sb.toString === "ScalaTest is fun!")
    assert(lb.isEmpty)
    lb += "sweeter"
    intercept[StringIndexOutOfBoundsException] {
      "concise".charAt(-1)
    }
  }
}



What can be done about this? Obviously a 13s wait makes test driven development pretty much impossible.

Thanks
