title: use specs2 in 'is' style with play2
body: <pre><code>class ServiceTest extends PlaySpecification with Mockito {
  
    override def is =
      s2"""
      This is Service Specification
  
      The Service  should create element in right way          $init
  
      """
    val metricId = 1
    val hashid = HashIdGenerator.hashId(metricId)
    def init = 1 mustEqual (1)
  
  }
  </code></pre>
  
  <p>The HashIdGenerator need play application start , the play doc shows we need get a play application in this way: <a href="https://www.playframework.com/documentation/2.1.0/ScalaTest" rel="nofollow">https://www.playframework.com/documentation/2.1.0/ScalaTest</a></p>
  
  <pre><code>  "Computer model" should {
  
    "be retrieved by id" in new WithApplication {
      // your test code
    }
    "be retrieved by email" in new WithApplication {
      // your test code
    }
  }
  </code></pre>
  
  <p>but i don't like this 'should in ' style , so how can i get a play application and keep using 'is' style at the same time .</p>
