测试自定义插件的portlet：BeanLocatorException和事务回滚的服务测试

Question

我的问题：

1. 我可以成功测试CRUD操作服务。我是做 上@Before插入[设置（）]和@After 同一数据的删除[拆解（）]，但展望未来，我需要支持事务 而不是插入和删除编写代码。

2. 我成功地获取我的实体的单记录，但是当我火了搜索查询或尝试获取我的实体，我得到的不止一个：

   com.liferay.portal.kernel.bean。 BeanLocatorException：BeanLocator尚未设置servlet上下文MyCustom的portlet

我遵循以下一些环节，以建立与Junit的Liferay的：

• Liferay wiki - How to use Junit to test Service in Portlets
• SO - Unit Testing in Liferay
• SO - Junit Testing DAOs rollback or Delete

我的环境

• 的Liferay 6.0.5 EE捆绑的Tomcat

• 的Eclipse太阳神与被判无期徒刑AY使用Junit4

• 我正在我的测试，在Eclipse本身 “蚁族” 的命令，但不 IDE 1.4通过键入Alt键 + 移 + X，牛逼。

这将是非常有益的，如果我能得到一些想法，如何去使用的交易使用JUnit（或至少一些想法，它是如何工作的Liferay），以及如何解决BeanLocatorException（或至少为什么会被抛出）

任何帮助将不胜感激。

我用于JUnit测试mockito框架并通过PortalBeanLocatorUtil.setBeanLocator(...) -methode注入服务。我认为这显然是用弹簧配置来做到这一点。在这里你有完整的例子如何使用它。这个例子是拍那就是好，所以，因为方法简单易懂。

package mst.unittest.example; 

import java.text.ParseException; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import org.junit.Before; 
import org.junit.Test; 

import com.liferay.portal.kernel.bean.BeanLocator; 
import com.liferay.portal.kernel.bean.PortalBeanLocatorUtil; 
import com.liferay.portal.kernel.exception.PortalException; 
import com.liferay.portal.kernel.exception.SystemException; 
import com.liferay.portal.model.User; 
import com.liferay.portal.service.UserLocalService; 
import com.liferay.portal.service.UserLocalServiceUtil; 

import static org.junit.Assert.*; 

import static org.mockito.Mockito.*; 

/** 
* @author mark.stein.ms@gmail.com 
*/ 
public class MyUserUtilTest { 


    private BeanLocator mockBeanLocator; 

    @Before 
    public void init() { 
     //create mock for BeanLocator, BeanLocator is responsible for loading of Services 
     mockBeanLocator = mock(BeanLocator.class); 
     //... and insert it in Liferay loading infrastructure (instead of Spring configuration) 
     PortalBeanLocatorUtil.setBeanLocator(mockBeanLocator); 
    } 

    @Test 
    public void testIsUserFullAge() throws PortalException, SystemException, ParseException { 
     //setup 
     SimpleDateFormat format = new SimpleDateFormat("yyyy_MM_dd"); 
     Date D2000_01_01 = format.parse("2000_01_01"); 
     Date D1990_06_30 = format.parse("1990_06_30"); 
     UserLocalService mockUserLocalService = mock(UserLocalService.class); 
     User mockUserThatIsFullAge = mock(User.class); 
     when(mockUserThatIsFullAge.getBirthday()).thenReturn(D1990_06_30); 
     User mockUserThatIsNotFullAge = mock(User.class); 
     when(mockUserThatIsNotFullAge.getBirthday()).thenReturn(D2000_01_01); 
     //overwrite getUser(...) methode so that wir get mock user-object with mocked behavior 
     when(mockUserLocalService.getUser(1234567)).thenReturn(mockUserThatIsFullAge); 
     when(mockUserLocalService.getUser(7654321)).thenReturn(mockUserThatIsNotFullAge); 

     //load our mock-object instead of default UserLocalService 
     when(mockBeanLocator.locate("com.liferay.portal.service.UserLocalService")).thenReturn(mockUserLocalService); 


     //run 
     User userFullAge = UserLocalServiceUtil.getUser(1234567); 
     boolean fullAge = MyUserUtil.isUserFullAge(userFullAge); 

     //verify 
     assertTrue(fullAge); 

     //run 
     User userNotFullAge = UserLocalServiceUtil.getUser(7654321); 
     boolean notfullAge = MyUserUtil.isUserFullAge(userNotFullAge); 

     //verify 
     assertFalse(notfullAge); 
    } 

} 

class MyUserUtil { 

    public static boolean isUserFullAge(User user) throws PortalException, SystemException { 
     Date birthday = user.getBirthday(); 
     long years = (System.currentTimeMillis() - birthday.getTime())/((long)365*24*60*60*1000); 
     return years > 18; 
    } 

} 

您也可以使用这种方法没有框架的Mockito，则必须创建一个类似手动MockBeanLocator模拟类。

引桥PowerMock

随着PowerMock你可以退位BeanLocator因为PowerMock可重写静态方法。这里有PowerMock相同的例子：

package mst.unittest.example; 

import java.text.ParseException; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.powermock.api.mockito.PowerMockito; 
import org.powermock.core.classloader.annotations.PrepareForTest; 
import org.powermock.modules.junit4.PowerMockRunner; 

import com.liferay.portal.kernel.exception.PortalException; 
import com.liferay.portal.kernel.exception.SystemException; 
import com.liferay.portal.model.User; 
import com.liferay.portal.service.UserLocalServiceUtil; 

import static org.junit.Assert.*; 

import static org.mockito.Mockito.*; 

/** 
* @author Mark Stein 
* 
*/ 

@RunWith(PowerMockRunner.class) 
@PrepareForTest(UserLocalServiceUtil.class) 
public class LiferayAndPowerMockTest { 

    @Test 
    public void testIsUserFullAge() throws PortalException, SystemException, ParseException { 
     //setup 
     SimpleDateFormat format = new SimpleDateFormat("yyyy_MM_dd"); 
     Date D2000_01_01 = format.parse("2000_01_01"); 
     Date D1990_06_30 = format.parse("1990_06_30"); 
     User mockUserThatIsFullAge = mock(User.class); 
     when(mockUserThatIsFullAge.getBirthday()).thenReturn(D1990_06_30); 
     User mockUserThatIsNotFullAge = mock(User.class); 
     when(mockUserThatIsNotFullAge.getBirthday()).thenReturn(D2000_01_01); 

     //overwrite getUser(...) by UserLocalServiceUtil methode so that wir get mock user-object with mocked behavior 
     PowerMockito.mockStatic(UserLocalServiceUtil.class); 
     when(UserLocalServiceUtil.getUser(1234567)).thenReturn(mockUserThatIsFullAge); 
     when(UserLocalServiceUtil.getUser(7654321)).thenReturn(mockUserThatIsNotFullAge); 

     //run 
     boolean fullAge = MySecUserUtil.isUserFullAge(1234567); 

     //verify 
     assertTrue(fullAge); 

     //run 

     boolean notfullAge = MySecUserUtil.isUserFullAge(7654321); 

     //verify 
     assertFalse(notfullAge); 
    } 

} 

class MySecUserUtil { 

    public static boolean isUserFullAge(long userId) throws PortalException, SystemException { 
     User user = UserLocalServiceUtil.getUser(userId); 
     Date birthday = user.getBirthday(); 
     long years = (System.currentTimeMillis() - birthday.getTime())/((long)365*24*60*60*1000); 
     return years > 18; 
    } 

} 

在这里，你发现PowerMock 1.4.12用的Mockito和JUnit包括依赖http://code.google.com/p/powermock/downloads/detail?name=powermock-mockito-junit-1.4.12.zip&can=2&q=

猜测：你真的需要测试的交易？或者只是关于数据库访问的业务逻辑？ 因为如果是这样，你可以尝试用EasyMock（或类似的）编写单元测试，避免访问数据库，但仍然测试功能
