本文介绍了两种在Java中使用Mock进行单元测试的方法，包括利用Servlet3.0 API创建Mock对象和使用Mockito库模拟请求、响应及session。示例代码展示了如何在测试前后设置session，并提供了分页查询和插入操作的测试用例。通过Mock测试，可以确保代码独立于实际环境，提高测试覆盖率。

一、方式一

//需要Servlet 3.0，如果项目是Servlet 2.5，引入测试依赖Servlet 3.0即可。
//MockHttpServletRequest request =new MockHttpServletRequest();
//MockHttpServletResponse response = new MockHttpServletResponse();
MockHttpSession session = new MockHttpSession();

依赖

<dependency>
	<groupId>javax.servlet</groupId>
	<artifactId>javax.servlet-api</artifactId>
	<version>3.1.0</version>
	<scope>test</scope>
</dependency>

如果不引入Servlet3.0会报错：

java.lang.NoClassDefFoundError: javax/servlet/AsyncContext
java.lang.NoClassDefFoundError: javax/servlet/SessionCookieConfig

二、方式二（未测试）

HttpServletRequest requestMock = Mockito.mock(HttpServletRequest.class);
HttpServletResponse responseMock = Mockito.mock(HttpServletResponse.class);
HttpSession sessionMock = Mockito.mock(HttpSession.class);
Mockito.when(requestMock.getSession()).thenReturn(sessionMock);

依赖

<dependency>
	<groupId>org.mockito</groupId>
	<artifactId>mockito-core</artifactId>
	<version>1.9.5</version>
	<scope>test</scope>
</dependency>

三、示例代码

package test.cms;

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.greaterThan;

import java.util.HashMap;
import java.util.Map;

import org.apache.commons.logging.Log;

import org.springframework.mock.web.MockHttpSession;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.urthink.framework.page.EuiPage;
import com.urthink.framework.web.UserSession;
import com.urthink.module.cms.entity.Catalog;
import com.urthink.module.cms.service.CatalogService;
import com.urthink.platform.authority.entity.User;

/**

@RunWith(SpringJUnit4ClassRunner.class) // 整合
@Rollback // 事务自动回滚
@ContextConfiguration(locations = {"classpath:spring-context.xml", "classpath:spring-mybatis.xml"}) // 加载配置
public class CatalogTest extends AbstractTransactionalJUnit4SpringContextTests {
	
	private static final Log log = LogFactory.getLog(CatalogTest.class);
	
	@Autowired
	private CatalogService catalogService;
	
	/**
	 * 测试前执行
	 */
	@Before
	public void beforeTest(){
		User user = new User();
		user.setId("1");
		
		//需要Servlet 3.0，如果项目是Servlet 2.5，引入测试依赖Servlet 3.0即可。
		//MockHttpServletRequest request =new MockHttpServletRequest();
		//MockHttpServletResponse response = new MockHttpServletResponse();
		MockHttpSession session = new MockHttpSession();
		
		session.setAttribute("user", user);
	}

	/**
	 * 测试后执行
	 */
	@After
	public void afterTest(){
		
	}
	
	/**
	 * 分页查询测试
	 */
	@Test
	public void pageListTest() {
		Map paramMap = new HashMap();
		paramMap.put("page", 1);
		paramMap.put("rows", 10);
		paramMap.put("orderBy", "id asc");
		EuiPage euiPage = catalogService.getPageList(paramMap);
		assertThat(euiPage.getTotal(), greaterThan(0L));
	}
	
	/**
	 * 插入测试
	 */
	@Test
	public void insertTest() {
		Catalog catalog = new Catalog();
		catalog.setParentId(14);
		catalog.setSiteId(2);
		catalog.setName("测试栏目");
		catalog.setDescription("测试栏目描述");
		catalog.setEnable("1");
		int r = catalogService.insert(catalog);
		assertThat(r, greaterThan(0));
	}
	
}
