Testing Tapestry pages and components with JUnit

According to the Tapestry documentation using PageTester is the appropriate way to do unit testing of Pages and Components: https://tapestry.apache.org/unit-testing-pages-or-components.html

But this seems similar to HtmlUnit style web testing as the interaction happens through a web browser like interface and not through the interface of the Page or Component.

Edit

I just tried a simple unit test for pages and it works quite well :

public class FooPageTest extends AbstractServiceTest{

    @Autobuild
    @Inject
    private FooPage fooPage;

    @Test
    public void setupRender(){
        fooPage.setupRender();
    }

}

AbstractServiceTest provides a test runner which provides the Tapestry dependency injection to the unit test class. With Autobuild you get the @Inject dependencies of the FooPage satisfied and for the component injections and @Property annotated elements you will need to figure out something else.
