タイル構成のビューを持つスプリングMCコントローラのテスト

Question

タイル構成のビューを持つコントローラをテストする方法はわかりません。

以下

が

import javax.inject.Inject; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import junit.framework.Assert; 

import org.junit.Before; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.springframework.context.ApplicationContext; 
import org.springframework.mock.web.MockHttpServletRequest; 
import org.springframework.mock.web.MockHttpServletResponse; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.TestExecutionListeners; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener; 
import org.springframework.web.servlet.HandlerAdapter; 
import org.springframework.web.servlet.HandlerExecutionChain; 
import org.springframework.web.servlet.HandlerInterceptor; 
import org.springframework.web.servlet.HandlerMapping; 
import org.springframework.web.servlet.ModelAndView; 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/servlet-context.xml", "file:src/main/webapp/WEB-INF/tiles-definitions.xml"}) 
@TestExecutionListeners(DependencyInjectionTestExecutionListener.class) 
public class BankControllerTest { 

    @Inject 
    private ApplicationContext applicationContext; 

    private HandlerAdapter handlerAdapter; 

    private MockHttpServletRequest request; 
    private MockHttpServletResponse response; 
    private BankController controller; 


    private ModelAndView handle(final HttpServletRequest request, final HttpServletResponse response) throws Exception { 
     final HandlerMapping handlerMapping = applicationContext.getBean(HandlerMapping.class); 
     final HandlerExecutionChain handler = handlerMapping.getHandler(request); 
     Assert.assertNotNull("No handler found for request, check you request mapping", handler); 
     final Object controller = handler.getHandler(); 
     for (final HandlerInterceptor interceptor : handlerMapping.getHandler(request).getInterceptors()) { 
      if (!interceptor.preHandle(request, response, controller)) { 
       return null; 
      } 
     } 
     return handlerAdapter.handle(request, response, controller); 
    } 

    @Before 
    public void setUp() throws Exception { 
     request = new MockHttpServletRequest(); 
     response = new MockHttpServletResponse(); 
     this.handlerAdapter = applicationContext.getBean(HandlerAdapter.class); 
    } 

    @Test 
    public void banksList() throws Exception { 
     request.setRequestURI("/banksList.do"); 
     request.setMethod("GET"); 
     final ModelAndView mav = handle(request, response); 
     // assertViewName(mav, "banksList"); 
     // assertAndReturnModelAttributeOfType(mav, "banksList", 
     // BankList.class); 
    } 
}

次のエラーを取得します。コントローラのテスト手法は何ですか？私のコントローラのテストケースを書くために他のフレームワークを使う必要がありますか？

Answer 1

Webコンテナを必要とするBeanでSpringコンテキストを読み込むことができないという問題があります。

コントローラをテストしたいだけなら、私はスプリングコンテキストなしで実際のユニットテストをお勧めします。つまり、コントローラが必要とするクラスのモックを作成する必要があります。

Answer 2

タイルビーンの構成には、lazy-init="true"を以下のように配置します。

class="org.springframework.web.servlet.view.tiles2.TilesConfigurer" lazy-init="true" 

Answer 3

テストする内容によって異なります。タイル・ビュー名が正しいことを確認しているだけの場合は、Spring Configurationを使用する必要はありません。しかし、ビューが解決されたかどうかを確認したり、モデルの属性、応答などをチェックしたい場合、SpringはMVCテストフレームワークを持っています。それはスタンドアローンでしたが、現在は3.2に含まれています。したがって、Spring 3を使用している場合は、SpringMVC Showcaseのテストを参照してください。私はタイルズでそれをまだテストしていませんが、可能であればビューリゾルバを設定する能力はあります。

Answer 4

私はその後、タイル構成

@Configuration 
public class TestConfigurtaion { 

    @Bean 
    public TilesConfigurer tilesConfigurer() { 
     TilesConfigurer configurer = new TilesConfigurer(); 
     configurer.setDefinitions(new String[] { "file:src/main/webapp/WEB-INF/views/tiles.xml" }); 
     configurer.setCheckRefresh(true); 
     return configurer; 
    } 
}
