Spring mvc + junit + mock

一 :直接测试方法

1. 首先开发一个基类，用于载入配置文件。以下所有的测试实现类都要继承这个类

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:dataSource-context.xml", "classpath*:persistence-context.xml",
		"classpath*:service-context.xml", "classpath*:mybatis-config.xml",
		"classpath*:src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml"
})
// 当然 你可以声明一个事务管理 每个单元测试都进行事务回滚 无论成功与否
@TransactionConfiguration(defaultRollback = true)
// 记得要在XML文件中声明事务哦~~~我是采用注解的方式
@Transactional
public class SpringMVCTestContent {

}

 2：对用户登入测试

 

      1）：用户登入Controller

 

 

	@RequestMapping(value = "/user", method = RequestMethod.POST)
	public String userLogin(@RequestParam(value = "user_id", required = false) String userid,
			@RequestParam(value = "passwd", required = false) String passwd, HttpServletRequest request, Model model) {
		if (userid == null || passwd == null) {
			model.addAttribute("loginerror", "查无此人");
			return "login";
		}
                  // ........ 
			}

     2):测试类

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.mock;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.ui.Model;

import com.chinacache.SpringMVCTestContent;

public class LoginTest extends SpringMVCTestContent {
	// 模拟request,response
	private MockHttpServletRequest request;
	private MockHttpServletResponse response;

	// 注入userController
	@Autowired
	private LoginController loginController;

	// 执行测试方法之前初始化模拟request,response
	@Before
	public void setUp() {
		request = new MockHttpServletRequest();
		request.setCharacterEncoding("UTF-8");
		response = new MockHttpServletResponse();
	}

	@Test
	public void testLogin() {
		Model a = mock(Model.class); //mock  model对象 
		assertEquals("login", loginController.userLogin(null, null, request, a));
	}
}

注意：如果是Maven项目，当执行Maven install时，可能会报错误，造成不能正确生成war包。此时需要在pom.xml中加入如下配置：

 

<project>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                 <configuration>
                     <testFailureIgnore>true</testFailureIgnore>
                 </configuration>
            </plugin>
        </plugins>
    </build>
</project>

 

 

注意：因为模拟request,response需要javax.servlet,AsycnContext类的支持，所以还需要导入javax.servlet3.0 Jar包的支持。

maven pom.xml配置代码如下：

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