How to unit test a custom Wicket component

Given this really simple Wicket component:

public class ProductImage extends WebComponent {

    public ProductImage(String id, Product p) {
        super(id, new Model(p));
        add(n开发者_运维问答ew AttributeModifier("src", true, new Model(p.getImage())));
    }
}

How to unit test it using WicketTester? Do I need a page?

---

In Wicket 1.5 there is #startComponentInPage(Component) which will create a page for you so you can test any kind of component.

I haven't actually done that (I've only tested panels), but startComponent() seems to be the way to do it.

Something like this:

Product product = new Product(/* initialize product here */);
ProductImage pi = new ProductImage("image", product);
tester.startComponent(pi);
tester.assertContains(Pattern.quote(product.getImage()));
