title: Hot Reload during Unit testing
body: <p>I develop right now a small flutter app. I think as everyone, I fell in love with the hot reload feature. </p>
  
  <p>So now I'm wondering if there is any possibility to have the same developer experience during unit test. Do have to turn a flag somewhere or is it right know just no possible.</p>
  
  <p>If is not possible, are there any plans to make it possible?</p>
