我没有使用任何框架,只是使用 maven war 模块,想使用 Juit 4 + Powermockito 测试 DAO 层(第一次)。
我的想法是当我调用 CustomerDao 来测试 createCustomer 时。该方法的第一条语句如下:
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建的 session 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", "xyz@pk.com",
"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:
- 当我运行测试类时出现错误:
org.hibernate.internal.util.config.ConfigurationException: Unable to perform unmarshalling at line number -1 and column -1 in RESOURCE hibernate.cfg.h2.xml. Message: unexpected element (uri:"http://www.hibernate.org/xsd/orm/cfg", local:"hibernate-configuration"). Expected elements are <{}hibernate-configuration>
但是如果我删除注释 @RunWith(PowerMockRunner.class)
那么我没有收到此错误。
- 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可以使用不同的 hibernate.cfg.xml
文件的 DAO 层。
最佳答案
问题似乎是 PowerMocks 类加载器。
Unable to parse hibernate.cfg.xml
我让 PowerMock、JUnit4 和 Hibernate 按照相同的原则在 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.*"})
全类示例:
org.hibernate hibernate-core 5.4.2.Final(编译)
junit junit:4.12(测试)
net.bytebuddy字节好友1.9.10(编译)
org.powermock powermock-module-junit4 2.0.2(测试)
com.h2database h2 1.4.199(测试)
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();
}
}
