我不知道如何测试具有tile配置视图的控制器。

以下是编写的单元测试用例

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);
    }
}

我收到以下错误

如何克服此错误。控制器的测试方法是什么？我是否需要使用任何其他框架来为我的控制器编写测试用程序

4 个答案:

答案 0 :(得分：1)

将tile lazy-init="true"置于tile bean配置中。

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

答案 1 :(得分：1)

这取决于您要测试的内容。如果您只是确保磁贴视图名称是正确的，那么它是正确的，您不必使用Spring配置。但是，如果您想查看视图是否已解析或检查模型属性，响应等，那么Spring有一个MVC测试框架。这是一个独立的，但它现在是3.2的一部分。因此，如果您使用的是Spring 3，则可能需要查看SpringMVC Showcase中的测试。我还没有用Tiles测试它，但它确实能够设置一个视图解析器，所以它应该是可能的。

答案 2 :(得分：0)

问题是您无法使用需要Web容器的bean加载弹簧上下文。

如果你只想测试控制器，那么我推荐真正的单元测试，没有Spring Context。这意味着您需要为控制器所需的类创建模拟。

答案 3 :(得分：0)

我使用以下内容在Spring启动时以tile为例加载测试用例

@RunWith(SpringJUnit4ClassRunner.class)   
@SpringApplicationConfiguration(classes = {MyApplication.class, TestConfigurtaion.class})   
@WebAppConfiguration
public class UserRepositoryTest {

    @Autowired
    UserRepository userRepository;

    @Test
    public void testCase{

    }   
}

然后是另一个瓷砖配置类

@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;
    }
}
