I upload all my code in https://drive.google.com/folderview?id=0B08GAyjqgToLfndlX2JRZG1ydnpxQzEyM29sQnhjZWp2QVIydzlMS2J2dFZ3a045R1BveWs&usp=sharing following is my code:

package ro
  import org.junit.Test
  /**
 * Created by roroco on 3/18/15.
 */
class TryTest extends GroovyTestCase {
      @Test
    def testSmth() {
        assert 1 == 1
    }
  }

and i run it with ‘gradle test --tests ro.TryTest’, it raise:
