测试自定义插件portlet:BeanLocatorException和Transaction roll-back用于服务测试

Question

我的问题:

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

2. 我成功获取了我的实体的单个记录,但是当我触发搜索查询或尝试获取多个实体时,我得到:

   com.liferay.portal.kernel.bean.BeanLocatorException:尚未为servlet上下文设置BeanLocator MyCustom-portlet

我已经按照以下一些链接来设置Junit与Liferay:

• Liferay wiki - 如何使用Junit在Portlet中测试服务
• SO - Liferay中的单元测试
• SO - Junit测试DAO回滚或删除

我的环境

• Liferay 6.0.5 EE与Tomcat捆绑在一起

• 带有Liferay IDE 1.4的Eclipse Helios使用Junit4

• 我在eclipse中使用"ant"命令运行我的测试,但不是通过输入Alt+ Shift+ X, T.

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(或者至少是为什么会被抛出)

任何帮助将不胜感激.

Answer 1

我用于JUnit测试mockito框架并通过PortalBeanLocatorUtil.setBeanLocator(...)-methode 注入服务.我认为使用弹簧配置显然可以做到这一点.这里有完整的示例如何使用它.这个例子是拍摄的,这很好,因为这种方法简单易懂.

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;
    }

}

您也可以在没有mockito框架的情况下使用此方法,然后您必须MockBeanLocator手动创建模拟类.

使用PowerMock的方法

使用PowerMock,您可以放弃,BeanLocator因为PowerMock允许覆盖静态方法.这是与PowerMock相同的示例:

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.*;

/**

 */

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