如何在wicket的测试中模拟点击AjaxButton？

import org.apache.wicket.ajax.markup.html.form.AjaxButton;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.util.tester.WicketTester;
import org.junit.Before;
import org.junit.Test;

public class MyPageTest {
    private WicketTester tester;

    @Before
    public void setUp() {
        tester = new WicketTester(new MyApplication());
    }

    @Test
    public void testAjaxButton() {
        tester.startPage(MyPage.class);

        // 创建MockAjaxButton对象
        AjaxButton mockButton = new AjaxButton("mockButton") {
            @Override
            protected void onSubmit(AjaxRequestTarget target) {
                // 模拟点击事件的处理逻辑
            }
        };

        // 将MockAjaxButton添加到当前页面中
        tester.getComponentFromLastRenderedPage("form:mockButtonContainer").add(mockButton);

        // 模拟点击AjaxButton
        tester.executeAjaxEvent(mockButton, "click");

        // 断言或验证测试结果
        // ...

        tester.assertRenderedPage(MyPage.class);
    }
}

public class MyPage extends WebPage {
    public MyPage() {
        Form<Void> form = new Form<>("form");
        add(form);

        // 创建AjaxButton并添加到表单中
        AjaxButton ajaxButton = new AjaxButton("ajaxButton") {
            @Override
            protected void onSubmit(AjaxRequestTarget target) {
                // 处理AjaxButton的点击事件
            }
        };
        form.add(ajaxButton);
    }
}

public class MyApplication extends WebApplication {
    @Override
    public Class<? extends WebPage> getHomePage() {
        return MyPage.class;
    }
}
