unit testing in Quarkus with a JAX-RS resource using the active record pattern

Question

I have this simple OrderResource class that I would like to create unit tests for. I'm qusing Quarkus with Hibernate and Panache. What I don't understand is how do i get the function getOrders in my test? How can I mock the response without running this through a live system? I've currently added the quarkus-panache-mock dependency but i can't figure out how to mock the resource

Should the return values come from some service class? and then be injected into the test?

@Entity
public class Order extends PanacheEntity {
    public Long id;
    public String summary;
    public String description;
}

@Path("orders")
public class OrderResource {

    @GET
    @Path("orders")
    public String getAllOrders() {
        return Order.listAll();
    }

    @POST
    @Transactional
    public Response create(Order order) {
        order.persist();
        return Response.created(URI.create("/orders/" + order.id)).build();
    }


}

I tried creating a test like this:

    @Test
    public void testCreateOrder() {
        OrderResource orderResource = new OrderResource();
        System.out.println(orderResource.getAllOrders().get(0).name); //uses the live system
    }

But this is not a unit test but rather an integration test since it takes data from the real database.
