Spring測試框架springContextTest

    ssh版本：spring4.2/struts2.3/hibernate4；除了一些必要的jar包外，使用spring自帶的測試框架，還要額外導入spring-test-4.2.2.jar。

junit使用的是junit4.7，相關測試代碼以下：

package TestContext;

import java.util.List;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import entity.User;
import service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:beans.xml")
@Transactional
public class ListActionTest extends AbstractTransactionalJUnit4SpringContextTests{
	
	
	private UserService userService;
	

	public UserService getUserService() {
		return userService;
	}


	@Resource
	public void setUserService(UserService userService) {
		this.userService = userService;
	}


	//@Rollback(true)默認true 
	@Test
	public void test(){
		User user = userService.getUser(50);
		System.out.println(user.getUname());
		
		List<User> users = userService.getUsers();
		System.out.println(users.size());
	}
	
}

run as junit Test時報錯：

報錯信息裏提到：

SpringJUnit4ClassRunner requires JUnit 4.9 or higher

後來換成junit-4.12.jar,運行報錯：

java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

原來 Since JUnit 4.11 the junit.jar itself has no Hamcrest classes，後來導入harmcrest-core-1.3.jar，繼續運行，ok!
