MassTransit Service Bus Configuration and Unit Tests

For MassTransit, when setting up a new service bus the endpoint/type must be declared; however, I am trying to remove that dependency so that when I do tests against the consumer I can utilize the loopback endpoint but once in production, it would use the actual msmq endpoint.

Below is an example setup of a new service bus:

public class ConsumerService
{
    IServiceBus _bus;

    public void Start()
    {
        // Initalize Service Bus
        _bus = ServiceBusFactory.New(x =>
        {
            //x.UseMsmq();
            x.ReceiveFrom("loopback://localhost/MyQueue");
            x.SetConcurrentConsumerLimit(1);
        });
        _bus.SubscribeConsumer(() => new MyConsumer());
    }

    public void Stop()
    {
        _bus.Dispose();
    }
}
