【问题描述】：

我不知道如何测试一个带有瓦片配置视图的控制器。

下面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

如何克服这个错误。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例

【问题讨论】：

标签： spring spring-mvc integration-testing

【解决方案1】：

将lazy-init="true" 用于tile bean 配置如下。

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

【讨论】：

【解决方案2】：

这取决于您要测试的内容。如果您只是确保平铺视图名称正确，那么您不必使用 Spring 配置是正确的。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。它是独立的，但现在是 3.2 的一部分。因此，如果您使用的是 Spring 3，您可能希望查看 SpringMVC Showcase 中的测试。我还没有用 Tiles 测试过它，但它确实有能力设置一个视图解析器，所以它应该是可能的。

【讨论】：

【解决方案3】：

问题是您无法使用需要 Web 容器的 bean 加载 spring 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。

【讨论】：

你能帮我指向一个我可以找到例子的博客
blog.vergiss-blackjack.de/2010/04/…，模拟框架：code.google.com/p/mockito 或 jmock.org
stackoverflow.com/questions/1401128/…

【解决方案4】：

我正在使用以下方法在 Spring Boot 中加载测试用例，以瓦片为例

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

    @Autowired
    UserRepository userRepository;

    @Test
    public void testCase{

    }   
}

然后是瓷砖配置的另一个类

@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;
    }
}
