Wicket Junit測試用例

Question

在我的wicket應用程序中，我想檢查我的主頁（HomePage.java）是否正確呈現。

我寫測試用例

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); 

} 
} 

我收到錯誤這樣

org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor 'public com.zipgrocery.pages.HomePage(org.apache.wicket.request.mapper.parameter.PageParameters)' and argument ''. Might be it doesn't exist, may be it is not visible (public).

我沒有在我的HomePage.java默認構造函數。那麼我應該如何編寫測試用例呢？

讚賞任何幫助或建議。提前致謝 ！

Answer 1

由於檢票1.5你剛纔打電話與參數的構造，所以你的情況

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

Answer 2

也許在這個古老的線程解決方案仍然有效：http://apache-wicket.1842946.n4.nabble.com/Passing-parameters-to-a-page-in-WicketTester-td1933884.html
