测试自定义插件portlet：BeanLocatorException和事务回滚以进行服务测试

Question

我的问题：

1. 我可以成功测试CRUD服务的运行情况。我在@Before [setUp（）]上执行插入操作，并在@After [tearDown（）]上进行相同数据删除操作，但今后，我需要支持事务处理，而不是编写用于插入和删除的代码。

2. 我可以成功获取实体的单个记录，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MyCustom-
portlet设置BeanLocator

我的环境

• 与Tomcat捆绑在一起的Liferay 6.0.5 EE

• 使用Junit4的带有Liferay IDE 1.4的Eclipse Helios

• 我正在我的测试，在Eclipse本身“蚁族”的命令，但不是通过打字Alt+ Shift+ X，T。

如果我对如何在JUnit上使用事务（或者至少对它在liferay中的工作方式有一些了解）以及如何解决BeanLocatorException（或至少为什么将其抛出）有一些想法，那将非常有帮助。

任何帮助将不胜感激。

Answer 1

我用于JUnit测试PortalBeanLocatorUtil.setBeanLocator(...)Mockito 框架，并通过-methode
注入服务。我认为这显然是通过弹簧配置来实现的。在这里，您有完整的示例如何使用它。这个例子很简单，所以很好，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 [e-mail]
 */
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框架的情况下使用这种方法，然后必须像MockBeanLocator手动创建模拟类。

使用PowerMock的方法

使用PowerMock可以退位，BeanLocator因为PowerMock允许覆盖静态方法。这是PowerMock的相同示例：

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，您发现了带有Mockito和JUnit的PowerMock
1.4.12，其中包括依赖项http://code.google.com/p/powermock/downloads/detail?name=powermock-
