JUnit

you can embed all detective stories into a JUnit test.

please create a Groovy junit file

  @Test
  public void testEchoTask(){
    story() "Simple Story with Echo Task" {
      inOrderTo "demostrate simple story"

      scenario "Echo parameters back" {
        given "a parameter" {
          parameterA = "This is the value"
        }

        when "run echo task"{
          runtask echoTask();
        }

        then "parameters will echo back"{
          echotask.parameterA << "This is the value"
        }
      }
    }
  }
