title: How to UnitTest Retry feature of MassTransit
body: <p>I config my application like this:</p>
  <p><a href="https://i.stack.imgur.com/WVkLs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WVkLs.png" alt="enter image description here" /></a></p>
  <p>It worked well, I want to add unit test for my consumer. So, I wonder, is there any way to set up the consumer to ReTry to an expect time in unit test. Like that:</p>
  <p><a href="https://i.stack.imgur.com/BxHBZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BxHBZ.png" alt="enter image description here" /></a></p>
  <p>Unfortunately, the consumer is not triggered by UseMessageRetry in StartUp configuration when run by unit test.</p>
  <p>Could you help me on this topic?. Thanks.</p>
