使用H2数据库的Junit 4.x + Hibernate 5.x.

问题描述 投票:3回答:1

我没有使用任何框架只使用maven war模块,并希望使用Juit 4 + Powermockito(第一次)测试DAO层。

我的想法是当我致电CustomerDao测试createCustomer时。该方法的第一个陈述如下:

Session session = HibernateManager.getInstance().getSessionFactory().openSession();

我想模拟这个调用,以便我可以使用以下代码提供我在测试类中构造的会话对象:

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.powermock.modules.junit4.PowerMockRunner;
import com.dao.CustomerDao;

@RunWith(PowerMockRunner.class)

public class CustomerDaoTest {

    private SessionFactory sessionFactory;

    @Mock
    CustomerDao customer=new CustomerDao();

    @Before
    public void setup() {
        sessionFactory = createSessionFactory();
        }

    @Test
    public void CustomerCreateAndDeleteTest() throws Exception {
        // Want to mock here
        int id=customer.createCustomer("Indian Customer", "India", "[email protected]", 
        "234567890", "AB");
        Assert.assertEquals(1, id);
     }

    private SessionFactory createSessionFactory() {
        Configuration configuration = new Configuration().configure("hibernate.cfg.h2.xml");// Using H2 for testing only
        sessionFactory = configuration.buildSessionFactory();
        return sessionFactory;
    }

}

问题是:

  1. 当我运行我的测试类时,我收到错误:

org.hibernate.internal.util.config.ConfigurationException:无法在RESOURCE hibernate.cfg.h2.xml中的第-1行和第-1列执行解组。消息:意外元素(uri:“http://www.hibernate.org/xsd/orm/cfg”,local:“hibernate-configuration”)。预期的要素是

但是如果我删除注释@RunWith(PowerMockRunner.class)然后我没有得到这个错误。

  1. 我如何模拟createCustomer()方法中的方法调用,如下所示:Session session = HibernateManager.getInstance().getSessionFactory().openSession();

请指导我如何编写单元测试用例来测试DAO层,它可以使用不同的hibernate.cfg.xml文件。

java spring hibernate junit4 powermockito

问题似乎是PowerMocks类加载器。

Unable to parse hibernate.cfg.xml

我让PowerMock,JUnit4和Hibernate按照相同的主体在JDK11中工作,并将以下内容添加到我的类中:

@PowerMockIgnore({"com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", "org.hibernate.*"})

全班示例: org.hibernate hibernate-core 5.4.2.Final (compile) junit junit:4.12 (test) net.bytebuddy byte-buddy 1.9.10 (compile) org.powermock powermock-module-junit4 2.0.2 (test) com.h2database h2 1.4.199 (test)

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", "org.hibernate.*"})
public class PowerMockHibernateTest {

    private SessionFactory sessionFactory;

    public PowerMockHibernateTest() {
    }

    @Before
    public void setUp() {
        sessionFactory = createSessionFactory();
    }

    @After
    public void tearDown() {
        sessionFactory.close();
    }

    private Session getNewSession() {
        return sessionFactory.openSession();
    }

    @Test
    public void getQuery() {
        Session session = getNewSession();
        session.createNamedQuery("PostEntity.All", PostEntity.class);
    }

    private SessionFactory createSessionFactory() {
        Configuration configuration = new Configuration().configure("hibernate.cfg.h2.xml");
        configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
        configuration.setProperty("hibernate.connection.driver_class", "org.h2.Driver");
        configuration.setProperty("hibernate.connection.url", "jdbc:h2:mem:test");
        configuration.setProperty("hibernate.hbm2ddl.auto", "update");
        return configuration.buildSessionFactory();
    }
}
