   * On the other hand, past underutilization could mean that "the server responsible for handling
   * the request has become less ready for future requests", i.e. its caches become stale, and
   * requests become more likely to trigger expensive operations (a more extreme case of this
   * example is when a server has just booted, and it is mostly busy with getting itself up to
   * speed).

  RecordedRequest request3 = server.takeRequest();
  assertEquals("/v1/chat/messages/3", request3.getPath());

  // Shut down the server. Instances cannot be reused.
  server.shutdown();
}
```

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.

		return err
	}
	x.ClientConversation = x.Client.NewConversation()
	return nil
}

// Step takes a string provided from a server (or just an empty string for the
// very first conversation step) and attempts to move the authentication
// conversation forward.  It returns a string to be sent to the server or an
// error if the server message is invalid.  Calling Step after a conversation
// completes is also an error.
