改札アプリケーションで、ホームページ（HomePage.java）が正しくレンダリングされるかどうかを確認したいと思います。

テストケースを書きました

public class TestMerchantProductPage extends TestCase {
private WicketTester tester = null;

@BeforeClass
public void testSetUp(){
    tester = new WicketTester();
    tester.startPage(HomePage.class);
}

@SuppressWarnings("deprecation" )
@Test
public void testPage(){
    tester.assertRenderedPage(HomePage.class);
    tester.startPanel(ItemOrderPanelBySearch.class);

}
}

このようなエラーが発生します

HomePage.javaにデフォルトのコンストラクターがありません。では、テストケースをどのように書くべきですか？

任意の助けや提案をいただければ幸いです。前もって感謝します ！

Wicket 1.5以降は、パラメーターを使用してコンストラクターを呼び出す必要があるため、この場合は

WicketTester tester = new WicketTester(YourApplication);
tester.startPage(new HomePage(YourParameter));
tester.assertRenderedPage(HomePage.class);

たぶん、この古いスレッドの解決策はまだ有効です：http: //apache-wicket.1842946.n4.nabble.com/Passing-parameters-to-a-page-in-WicketTester-td1933884.html
