title: Setting akka TestKit default timeout in code
body: <p>What's the correct way to set a default timeout for <code>TestProbe.expectNoMsg()</code> in code not in config?</p>
  
  <p>I'm aware that I can define <code>akka.test.single-expect-default</code> in application.conf, but this applies to all tests in my module.  Or something like</p>
  
  <pre><code>ActorSystem(.., ConfigFactory.parseString("{akka.test.single-expect-default = 0}"))
  </code></pre>
  
  <p>in code works, but I'd expect to be able to set this timeout like</p>
  
  <pre><code>implicit val timeout = Timeout(100 millis)
  </code></pre>
  
  <p>which I've seen references to but is not being recognized.</p>
  
  <p>My test is</p>
  
  <pre><code>@RunWith(classOf[JUnitRunner])
  class MySuite extends path.FunSpec with Matchers {
  
      implicit val system = ActorSystem("MySuite")
  
      val probe = new TestProbe(system)
  
      describe ("timeout") {
          println("Waiting..")
          probe.expectNoMsg()
          println("Waited")
      }
  }
  </code></pre>
