Wicket Junit测试用例

Question

在我的wicket应用程序中，我想检查我的主页（HomePage.java）是否正确呈现。

我写测试用例

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); 

} 
} 

我收到错误这样

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).

我没有在我的HomePage.java默认构造函数。那么我应该如何编写测试用例呢？

赞赏任何帮助或建议。提前致谢 ！

Answer 1

由于检票1.5你刚才打电话与参数的构造，所以你的情况

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

Answer 2

也许在这个古老的线程解决方案仍然有效：http://apache-wicket.1842946.n4.nabble.com/Passing-parameters-to-a-page-in-WicketTester-td1933884.html
